Statement 1: An alternating current shown magnetic effect.
Statement 2: Alternating current varies with time .

A

Statement 1 is true, statement 2 is true, Statement 2 is the correct explanation for statement 1.

B

Statemet 1 is True, Statement 2 is true , Statement 2 is NOT the correct explanation for Statement 1

C

Statement 1 is True, Statement 2 is False.

D

Statement 1 is False, Statement 2 is true

Text Solution

Verified by Experts

The correct Answer is:
B
Like direct current, alternating current also porduces magnetic fields. But the magnetic and direction of the field goes on charging continuously with time.
