Q31 of 36 Page 120

If by passing the current of 10 milliampere in a wire a potential difference of 2.5 volt is produced across the end of wire. Calculate the resistance of wire.

Now we are given with the Potential difference(V) across a wire which is 2.5 volt, when 10mA of current(I) passes through it and we have to find the resistance of the wire,

By using Ohm’s law equation, which is, V = IR,



Now putting values in the equation,
