When the AC source is connected across a resistor?
Correct answer: C. Current and voltage are in same phase
- A. Current leads the voltage in a phase
- B. Current lags behind the voltage in a phase
- C. Current and voltage are in same phase
- D. Depends upon resistance
Explanation
Here is the explanation of the correct option Current and voltage vary sinusoidal with same frequency and are in phase with each other

About AC Through Resistor, Capacitor and Inductor
Alternating current through a resistor, capacitor and inductor involves phase relationships between voltage and current, reactance, impedance and energy transfer. A resistor keeps voltage and current in phase, while a capacitor and inductor produce opposite phase shifts, a distinction used in circuit diagrams and numerical calculations.
