Question

Calculate the heat in calorie if 200 V potential difference is applied across a resistor

for 5 minute if the current is 3 A​

Answer 1

Answer:

V = 200 v

T = 5 min = 5×60 = 300 seconds

I = 3A

Therefore, H = V×I×T

H = 200 × 3 × 300

H = 180000 J

or

H = 18× 10⁴ J.

Hope u got it....
