If Irms × Vrms = 100 watts, then Ipeak × Vpeak= ?
Correct answer: B. 200 watts
- A. 100 watts
- B. 200 watts
- C. 282.84 watts
- D. None
Explanation
The average power is P (avg) = I (rms) × V (rms) = 100 W. The peak power is P (peak) = I (peak) × V (peak) . Since I (rms) = I (peak) /√2 and V (rms) = V (peak) /√2, we have P (avg) = (I (peak) × V (peak) )/2, which means P (peak)= 2 × P (avg) = 2 × 100 W = 200 W.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
