Question

potential difference of 10 volts is needed to make a current of 0.02 empire flow through a wire what potential difference to make a current top 250 milli
ampere flows to the same wire​

Answer 1

Answer:

125 V

Explanation:

Resistance of given wire R is given by

R = V/I = 10/ 0.02= 500 ohm

now , if I = 250 mA then

V = IR = 250 *10^-3 * 500 = 125 V
