Application +4 | -1

A direct current of

4 \mathrm{~A}

and an alternating current of peak value 4 A flow through resistance of

3 \Omega

and

2 \Omega

respectively. The ratio of heat produced in the two resistances in same interval of time will be :

View answer and explanation

Correct option: B

3: 1

Option B (

3: 1

) is correct because the heat produced is proportional to the square of the current, and the RMS value of the AC current is used for heat calculations.
