Question

Derive the formula for heat produced when a current I is passed through a resistor R for time t.​

Answer 1

Explanation:

I=V/R. Heat generated per second, Heat. H=V×I×t

Answer 2

Answer:

Heat produced ,H=I

2

Rt

(b) Given : R=20ohm,I=5amp,t=30s

We know that H=I

2

Rt

H=5

×20×30

H=15000J

hope your answer
