Question

calculate the amount of heat produced by a resistor of 200 ohm ,when a current of 3 A is passed through it for one minute​

Answer 1

Given:

Resistance = 200ohm

Electric current = 3ampere

Time = 1min=60sec

To Find :

Amount of heat produced

Solution:

$\huge\bold\red{\mathbb{H= {I}^{2}RT}}$

by putting the value in above formula ,we get:

$\bold\red{\mathbb{》H={3}^{2}×200×60}}$

$\bold\red{\mathbb{》H=9×200×60}}$

H = 108000 joule
