Assertion: If an inductor coil is connected to DC source, the current supplied by it is `I_(1)`. If the same coil is connected with an AC source of same voltage. Then current is `I_(2)`, then `I_(2) lt I_(1)`.
Reason: In AC circuit, inductor coil offers more resistance.

A

If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
`Z_(DC) = r`
`Z_(AC) = sqrt(r^(2)+X_(L)^(2))`
Here, r= internal resistance of the coil.
Also, `I alpha I/Z`
`therefore I_(1) gt I_(2)`
