Introduction to Voltage, Current, Resistance and Power Explained for Beginner

About: Advanced and latest technology tutorials on my youtube channel and now i started instructable so i will post one by one latest tutorial.

This video is related to basic electronics terms, and easy to understand, i will try to explain easily with water analogy concept, so it's helps to understand batter then theory, so please see this video for clear your concept about Current, Voltage, Power and Resistance.

If you like this video then please subscribe my YouTube channel, i will upload mode easy tutorials.


Step 1: Voltage

Pressure = Voltage(measured in Volts)

The pressure at the end of the hose can represent voltage. The water in the tank represents charge. The more water in the tank, the higher the charge, the more pressure is measured at the end of the hose.

Step 2: Current

Flow = Current (measured in Amperes, or “Amps” for short)

We can think of the amount of water flowing through the hose from the tank as current. The higher the pressure, the higher the flow, and vice-versa. With water, we would measure the volume of the water flowing through the hose over a certain period of time.

Step 3: Resistance

Hose Width = Resistance

It stands to reason that we can’t fit as much volume through a narrow pipe than a wider one at the same pressure. This is resistance. The narrow pipe “resists” the flow of water through it even though the water is at the same pressure as the tank with the wider pipe.
