In an A.C circuit with resistor only, the current and voltage have a phase angle of:
Correct answer: B. 0o
- A. 90o
- B. 0o
- C. 180o
- D. None of these
Explanation
This is the correct answer. In a purely resistive A.C circuit, the current and voltage are in phase with each other, meaning they are synchronized and have no phase difference. They reach their maximum values and change direction simultaneously.

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.
