Do you Know that you can lookout for emergency power from your telephone Lines? Yes it's True that you can do it and in a very few simple steps. In electricity cut off also, this system works 24/7. You can take off power from telephone lines whenever you want. After all, who doesn't want Free Electricity?
I will tell you some applications of the telephone line power and will discuss about its specifications. We will do all this with the help of Telephone Line Cable RJ11 CABLE. This is easily available at any place and also widely used.
Using the power from telephone lines is extremely easy and anyone can do it. However Telephone Department do not mind the electricity usage.
Go on Reading and I am Sure you would find it interesting.
PLEASE ADD TO FAVORITE AND VOTE IF YOU FIND THE INSTRUCTABLE USEFUL.
Step 1: Materials Required
Step 2: RJ 11 Cable
RJ11 Cable is also known as Telephone Line Cable and it is easily available at any place. You can find one connected to your Landline. By this cable, your phone can remain active.
This cable has two wires inside carrying some voltage and current. With no cells also your phone can live with the power of Telephone Line.
Step 3: Splitting
Splitting is the most necessary and somewhat difficult job to do so. First of all, cut out one of the connector from the RJ 11 Cable.
Then take out the outer covering of the wire. The two wires you can now see are extremely delicate. These are the wires that carries voltage and current and it is difficult to take out its copper part of inside.
Now, expose the copper part and your cable is ready to power.
Step 4: Voltage
After getting the cable ready connect the split wires to the terminals of the multi meter and check the voltage.
You will notice that the display shows around 45 volts. The voltage are really much in amount.
Step 5: Current
Now, put the terminal of the multi meter up and tune it to get the reading of the current.
You will get current between 0.02A and 0.03A which is very low in amount.
Step 6: Some Mathwork
As we have seen our voltage and current. We have assumed to have more power but as in this case amperes are less so voltage seems to be little. For the accuracy we have to check the power. However, getting voltage is much easier than to get power.
Here the voltage is 45 Volts and current is between 0.02A and 0.03 A. So, let us take it as 0.025 Ampere. Now, the Power we get is:
Power = Voltage x Ampere
= 45 x 0.025
= 1.125 Watts
Step 7: Lighting LED
As we have seen, we got 1.125 Watts which is enough to light LED. So, lets light LED.
In order to light LED, just connect the LED to the telephone Line Cable's Wires that we have split earlier.
You can connect the LED in any polarity. It really doesn't matter in which polarity you are connecting LED. It will light up brightly.
Step 8: Charging a Cell
Charging a cell from telephone line power can help you do many things. Just attach the split RJ11 Cable to the cell holder or directly to the cell.
It can take 4-5-6 hours to charge completely to 1.2v and 0.5 A.
Step 9: Mobile Charging
Mobile Charging is the main issue for everyone. It is difficult to directly charge the cell from the telephone line. However, it is not impossible. But the simple trick is to owe a DC-DC Boost Converter. In input you should connect your charged cell from the previous step.
Image here shows a DC-DC Boost Converter.
You can now charge the mobile by simply connecting Data Cable from Converter to mobile phone.
You can also charge it in your simple way and also this is not the only way.
