Assertion: In series `LCR` circuit resonance can take place. Reason: Resonance takes place if inductance and capacitive reactance are equal and opposite.A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion.B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.C. Assertion is true but Reason is falseD. Assertion is false but Reason is true |
Answer» Correct Answer - 1 In a series `R-L-C` circuit resonance can takes place, because at a particlar frequency of ac source, the impedance can be minimum. `Z = sqrt(R^(2) + (X_(L) - X_(C ))^(2))` Resonance means current is maximum `implies` Inpdedance is minimum `implies X_(L) = X_(C )`. |
