Q1:

The total power in a certain circuit is 12 W. Each of the four equal-value series resistors making up the circuit dissipates

A 12 W

B 48 W

C 3 W

D 8 W

ANS:C - 3 W

In series connection voltage across each resistors is different.
The Power eqn is p=vi.

So voltage in each resistors is different.
But current is same in series connection.
So, Why not power in each resistors is different?
