    Using telephone line as power source?

    Re: telephone line as power thanks laktronics! voltage is 0. I arranged another test: With only one 10 ohm resistor, the current was:(I=59 mA). I think this is the maximum current that we can take from tel line. I need at least 120 mA to turn on the lamp. Can I amplify the current? how?
