Question

Calculate the resistance of conductor if 100mA current flows through a conductor when a potential difference of 2.0V is applied across its ends.

Answer 1

Answer:

R  = 20 ohm

Explanation:

V = 2 V and I = 100mA = 100 x 10⁻³ A = 0.1 A

According to Ohm's law,

         R = V / I

            = 2 / 0.1

            = 20 / 1    (after conjugating with x10/10)

          R  = 20 ohm
