Review the verified answer and explanation for this PTS Pakistan Testing Service past-paper question on CampusFin.

The total power in a certain circuit is 12 W. Each of the four equal-value series resistors making up the circuit dissipates Answer: 3 W

Since the four resistors have equal resistance and are connected in series, they carry the same current and therefore dissipate equal power. Thus, 12W÷4=3W per resistor.
