Question

An ac source is connected to a resistive circuits. Which of the following is true

• A. Current leads the voltage and both are in same phase
• B. Current lags behind the voltage and both are in same phase
• C. Current and voltage are in same phase
• D. Any of the above may be true depending upon the value of resistance

Answer 1

The correct option is C

Current and voltage are in same phase

In a pure ohmic AC Resistance, the current and voltage are both said to be “in-phase” as there is no phase difference between them. The current flowing through the resistor is directly proportional to the voltage across it.
