In a resistive A.C circuit, instantaneous values of voltage and current are:
Correct answer: A. In phase
- A. In phase
- B. Out of phase
- C. Lead each other
- D. None of these
Explanation
In a resistive AC circuit, the correct option "in phase" means that the instantaneous values of voltage and current reach their maximum and minimum points simultaneously during each cycle.

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.
