My friend took apart his broken Kenwood amplifier. He used his multimeter to find the broken part, then removed the RM4Z rectifier diode. I've been searching for about an hour, but I cannot find any websites that sell the RM4Z diode. The closest I have found was one from Hitachi, but I read that the RM4Z was from a Chinese company. Suggestions?

Dear Fella's I'm having problem with my Solar Panel charger, because I made a solar charger but in times of bad weather, my battery charge keeps losing out. I have known about the function of the LOW VOLTAGE DISCONNECT which requires a particular diode or something that has to be connected to the panel in series towards the battery charger. Can anyone please help me find out what particular diode should I use in order for me to have the LVD function. Guys your help would mean a lot for my experiment and hopefully I could post it here as soon as it is done. Thanks in advance...

If you have a high voltage diode that is rated to low for your power supply, can you conect several of them to mach your power supply. For example take 5 5kv diodes and connect them to make a 25kv diode.

If I were to cut up a pair of headphones for the wiring, would I be able to us them to power an LED diode and connecting one end of the chopped off wiring to the LED and the other to a 9V battery. Would it work?

Hello. I'm biginner and I need very very simple project, I mean the simplest possible. I need to make something in digital electronics, something using protoboard and some diodes, transistors and resistors and use that to make something useful but very simple... can you please think of something that is so simple and let me know?

Hi there, I am looking to design a circuit with: • Has 10 LEDs o 5 LEDs in Series, with two of these sets connected in parallel. • I want the capability of the LED array to illuminate if one end of the PCB is powered by the positive and the other end is in contact with the negative. And vice-versa, meaning the first end is now touching negative with the other end in contact with positive. o I was told that I can use diodes, but I’m not sure by what configuration. I've attached something I've found online. Will this work? if so, can you provide an explanation of how it works?

Actually, I want to make a Coil Gun for which I require high Current and EMF. So, I went online looking for step-up generators but they are too expensive! So, I thought that why not convert my home output (220V AC) to DC and use it. Please tell me how to make a circuit that converts 220VAC to 220VDC and what components are required. I currently have the following components: 1. Capacitor: 350SV 160uF 2. 1N4007 Rectifier Diodes x10 3. AC Capacitor 250V 1.1uF And I have many more components such as transistors, capacitors, etc. I'll try to get the components that you tell me to, But please help me!!

I want to construct a panel with a 10-position rotary switch that lights a vertical column of lights or LED's. At position 1 the bottom light is on, at position 2 both lights 1 and 2 are on. At position 8, lights 1 through 8 are all on until at position 10 all 10 light are on. The bottom lights will be green... then middle lights yellow, and finally red lights at the top. I was going to use LED's but for 10 it seems I may need 24v supply? If I use 6-volt lamps, maybe I can get then to stay on with a 6-volt lantern battery or 9v battery ? Can I simply use a rotary switch and blocking diodes to keep the next light from coming on too soon? This is such a simple idea but I have not found a simple solution yet - any help will be very much appreciated.

I want to make a voltage mutiplier circuit to get 30kV+ DC from 12kV AC, I'm not sure what type of capacitors to get or diodes. Also how many times does it multiply the voltage, for each set of 2 diodes and 2 capacitors

I recently salvaged a motherload of switches and other random electrical parts from a broken dvd player. i found a black cilinder with a silver band painted around it. i went online and found out its a diode but it did not clarify what its function is to a extent that a less experienced person would understand it just tell me what does it do and whats it used in (put it in lamens terms so i can get a good understanding)

Hello: My name is Charles and I am 51 years old,all of this Computer Technology is all NEW to me as I am OLD SCHOOL if you know what I mean.I have had a Nervous Breakdown due to Stress,and have lost a lot of my Technical Memory.I am trying to pick back up on the Electronics for a pass-time,but things don't seem to make sense like they did before.I wanted to know how I can ask questions I have about the Electronics I am wanting to work on.As of right now,I need to see if someone can explain when using OHM's Law (Power is equal to Voltage of your Input times the Current needed in your Circuit).I have a 3 Watt Red L.E.D. which should run at 2.5-3.0 Volts with a 700 Milliamp Current.If using a 3 Volt supply times .700 would equal a 2.18 Watt Power for the Resistor.That does not sound right to use a 4 Ohm - 2 Watt Resistor for a 3 Volt Input.Is this really right or have I gotten confused somewhere?Thank you very much if you can help me out,Sincerely Charles.

I'm making a resin block lighting thing for my dorm room, but the lights are too bright to look directly at (and it's meant to be looked at). I decided to make a 555 dimmer circuit, and I used these plans. http://www.555-timer-circuits.com/led-dimmer.html when I built it, however, the LED stayed off. I couldn't figure out what was going on until I touched the two diodes in the circuit and noticed that the small current leaking through my skin caused the LED to blink slowly. I turned one of the diodes around, and lo and behold, the dimmer worked as expected. so what I want to know is: what was the purpose of the diodes in the original diagram? was the positioning of the diodes just an error in the design? should I run with what I have now (since it works), or do something different?

Hi, here is a circuit that i found in a device .. all i know is that this circuit provides 5.6v constant output at the "output" labelled in the image and takes AC voltage (220V r.m.s. and 50 Hz ). The labels on the diodes were not visible so i used random diodes in the simulation just one thing that the diode labeled "D3" is a zener diode. further that the capacitor is polypropylene film it reads as (1.1k 250v). i don't know weather it is 1.1kF or what because i think its not possible so i have attached an image of the capacitor too. can some one explain how this thing works ?? IN Simulation when i set the value of the AC to 6Vpeak and 50Hz the result is as it is in real life . but when i change the value to 320VPeak(220V r.m.s) the result varies and goes up-to very high values .. it is awesome because it converts ac to dc without any transformer or something so kindly take a look and do tell if u find out something .

Hi all,I'm working on a project where I will have two DC generators that are being powered by spinning turbines. These turbines will be spinning at different speeds and these speeds may vary over time (i.e. the voltage from the DC sources will almost always be different). There will also be instances where one isn't producing any voltage at all.I was wondering what it the best way to connect them? Should they be in series or in parallel? Should there be diodes?After they are connected the DC power will be fed into an inverter and converted to AC power.Thanks for any help!

I am trying to make a power 100-200kv power supply. I plan to do this by putting the positive output of a 7.5 kv flyback transformer through a cockroft walton multiplier. I have never done something like this before, so I am not completely sure about everything. I plan to make the multiplier with 14-15 stages. I thought that it would be okay to use 10 kv DC 1000pf ceramic disk capacitors in the multiplier. One thing I'm not sure about though is whether or not the flyback outputs DC or AC electricity. I assume it is DC since the input is rectified, but if it still is producing AC then I should probably use 15-20kv rated caps. The main thing is that I don't know what diodes to use. I thought I would use 1N4007 or something similar but the peak reverse voltage is only 1 kv. Does anyone know what type of diode to use, and where to get it at a reasonable price (below $2 per unit preferably)?

So I have a 5mw laser diode module that I am trying to get open so that I can install a 250 mw diode in its place. Problem is, the diode won't come out, the manufacturer glued it in, and I keep buying new modules from different sellers only to find inexplicably the stupid diode backing slathered in glue. Is there a way of getting this thing out? I don't care if the diode is broken, I don't need it, but I want the driver intact.
