Question

ample 12.11
100 J or heat is produced each second in a 4 resistance. Find the
potential difference across the resistor​

Answer 1

Answer:

The produced heat is given as,

H=I² × rt

100=I² × 4×1

I²=25A

I = 5

The potential difference is given as,

V=IR

=5×4

=20V

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