A resonance curve for an RLC series circuit is a plot of frequency versus
Correct answer: D. Reactance
- A. Voltage
- B. Current
- C. Impedance
- D. Reactance
Explanation
1 MWh = 10 W × 3600 s = 3.6×10 J = 3.6 GJ. Thus option D is the correct conversion.

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.
