Question

A current of 3 A is maintained in a resistor, 36000 joules
of energy is required to move the charge through the
resistor per minute. Calculate the potential difference across the resistor.
​

Answer 1

Explanation:

Heat is generated = I² x R x t

36000 = V x I x t

= V x 3 x 60

V = 36000/ 180 = 3600/ 18 = 200v
