generate the greatest amount of heat when a current
flows from A to B ?
p=2 ohm
Q=4 ohm
А
B
ww
R=1 ohm S=2 ohm
1) Q
2) S
3) P
4) R​

Answer 1

Explanation:

The resistance which generate maximum amount of heat in the given circuit is the resistance of 4 Ohm. Hence the correct option to the given question is option number b.
