What is a characteristic of power in a series circuit?

In a series circuit, the total power is determined by summing the individual power dissipated by each resistor or component in the circuit. This is because, in a series configuration, the current that flows through each component is the same. The power for each component can be calculated using the formula ( P = I^2 R ) or ( P = V^2 / R ), where ( P ) is power, ( I ) is current, ( V ) is voltage, and ( R ) is resistance.

Since the current is constant in a series circuit, the power contribution from each resistor accumulates, leading to the total power being the sum of all individual power contributions. Thus, stating that the total power in a series circuit is found using the sum of the individual powers accurately reflects how power behaves in such circuits. Factors such as voltage drops across each component also support this characteristic, further confirming that the overall power consumed is derived from the aggregation of the individual components' power.
