Which current can pass through a capacitor continuously:
Correct answer: C. Alternating current
- A. Direct current
- B. Electronic current
- C. Alternating current
- D. Both (a) and (b)
Explanation

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.
