Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The current drawn by the motor lags behind the voltage applied.
Reason (R): Motor is an inductive load.
In light of the above statements, choose the correct answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Inductive loads make current peak after voltage peaks.

Answer 1

The Correct Option is A

Step 1: A motor is an inductive load, so it stores energy in its magnetic field before releasing it back to the supply each cycle.
Step 2: Because of this inductive nature, the current waveform reaches its peak after the voltage waveform, so the current lags the voltage. This is exactly the Assertion (A).
Step 3: The Reason (R) that a motor is an inductive load is the correct physical cause of this current lag, so (R) explains (A) correctly. Both (A) and (R) are true and (R) is the correct explanation of (A).
