Ohm's Law
AIM :-A voltmeter, a current meter, and an unknown resistance etc. are given to you. Prepare an appropriate circuit to verify Ohm’s law. With appropriate values of current and voltages, only with the help of calculations, determine the value of unknown resistance.
PRINCIPLE : Potential difference in a conductor produces electric current.
APPARATUS :-
A unknown resistance,
a voltmeter (0 - 10 V),
a milliammeter (0 - 500mA), a battery,
a rheostat,
a tap key,
connecting wires.
