Question

100J heat is produced each second in a 40 ohm resistance. Find the potential difference across the resistor.

PLEASE ANSWER THE ABOVE QUESTION AS SOON AS POSSIBLE.​

Answer 1

Answer:

20

Explanation:

The produced heat is given as,

H=I

2

Rt

100=I

2

×4×1

I=25A

The potential difference is given as,

V=IR

=5×4

=20V

Thus, the potential difference across the resistor is 20V.
