Different combination of 3 resistors of equal resistance R are shown in the figures. The increasing order for power dissipation is:
A
P B < P C < P D < P A
B
P C <P D <P A < P B
C
P C < P B < P A < P D
D
P A <P B <P C < P D
Text Solution
Verified by ExpertsThe correct answer is:
C
The resistances can be calculated as
For second circuit
For third circuit
For fourth circuit
The formula for power is given by P = I 2 R. Clearly,
P D >P A >P B >P C
