Three resistors of equal resistance are arranged in four different combinations, as shown below. Arrange the combinations in increasing order of power dissipation if it is known that each combination carries the same current.
Text Solution
Verified by ExpertsThe correct answer is:
A
III 
II 
IV 
I
Current is same, so 
In the first case, it is 
, in second case it is 
, in the third case it is 
and in the fourth case the net resistance is 
.
