Explanation / Answer

1) for the identical resistance

as the power in resistance = I^2 * R

as the current in C is more than A and B

PC > PA = PB

the correct option is PC > PA = PB

2)

as the power in resistance = I^2 * R

as the current in C is more than A and B

PC = I^2/R

PB = PA = (I/2)^2 * R

3)

for the changed circuit

C is shorted, and there will be zero current in it

the ranking will change.

4)

C is shorted, and there will be zero current in it while current in A and B will equal to each other
