Assertion : An inductor coil normally produces more current with `DC` source compared to an AC source of same value of rms voltage. Reason : In `DC` source, applied voltage remains constant with time.A. If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.B. If both Assertion and Reason are true but Reason is not the correct explanation of AssertionC. If Assertion is true, but the Reason is false.D. If Assertion is false but the Reason is true. |
Answer» Correct Answer - B `I_(DC)=V_(DC)/r(r="internal resitance of inductor") ` `I_(AC)=V_(AC)/Z=V_(AC)/sqrt(r^2+X_L^2)` If `V_(DC)=V_(AC)`, then `I_(DC)gtI_(AC)`. |
