Question

Which of the following statements are true concerning AC circuit that contains both resistance and inductance? A. The current and voltage will be in phase., B. The current will lead the voltage ., C. The current will lag the voltage. D. The voltage will lag the current.

Answer 1

The current will lag the voltage in AC circuit that contains both resistance and inductance.

Answer: C

Explanation

There is no inductance only circuits in reality.

The circuits containing inductance has also a lower amount of resistance.

The current flows in both resistance and inductance.

There is a drop in the total voltage in resistance and inductance giving rise to the voltage applied in the coil when connected in a series.

An example being inductance coil an AC circuit connected to both resistance and inductance in series.

From the vector diagram, this conclusion can be drawn.
