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. |
Answer» Correct Answer - 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)` |
