Question

An A.C. source is connected to a resistive circuit. Which of the following is true?

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

Hint:

In resistive circuits, current and voltage are always in phase with each other.

Answer 1

The Correct Option is C

Step 1: Analyze the behavior in a resistive circuit.
In a purely resistive circuit, the current and voltage are always in phase, meaning they reach their maximum and zero points simultaneously.
Step 2: Conclusion.
Thus, in a purely resistive circuit, the current and voltage are in phase.
Final Answer: \[ \boxed{\text{Current and voltage are in same phase}} \]
