Which of the following statement is true both for a series and a parallel D. C. circuit?
Correct answer: D. Power are additive
- A. Elements have individual currents
- B. Currents are additive
- C. Voltages are additive
- D. Power are additive
Explanation
Power is additive in both series and parallel circuits because total power equals the algebraic sum of the powers absorbed or supplied by individual elements. Currents and voltages are not generally additive in the same way for both circuit arrangements.
