Question

Calculate the heat energy produces when 1A current flows through 100 R resistence wire for 1 hour

Answer 1

Answer: 360 KJ

Explanation:

The heat energy produced by the current I flowing through the resistance R in time t is given by,

$H = I^2 R t$

Here, I = 1 A, R = 100 ohm, t = 1 hour = 3600 s.

$H = 1^{2} \times 100 \times 3600 ~~J = 360000 ~~J = 360 ~~KJ$
