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

Correct Answer :

Option C: Current and voltage are in same phase

Explanation :

when resistance is connected to AC source, then current and voltage are in same phase.

In a pure oh-mic AC Resistance, the current and voltage are both “in-phase” as there is no phase difference between them.

The current flowing through the resistance is directly proportional to the voltage across it with this linear relationship in an AC circuit being called Impedance.

Answer 2

Option C is correct.

Current and voltage are in same phase.
