The algebraic sum of potential drops across the various elements in LCR-circuit is not equal to the applied voltage. Why?

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : In a LCR-circuit, the algebraic sum of the potential drops across the circuit elements is always equal to the applied mains voltage. Reason : The potential drop across the resistane is equal to the sum of the potential drops across the inductor and capacitor.

Answer the following questions: In any ac circuit, is the applied instantaneous voltage equal to the algebraic sum of the instantaneous voltages across the series elements of the circuit? Is the same true for rms voltage?

The given circuit diagram shows a series LCR circuit connected to a variable frequency 230 V source. How do you explain the observations that the algebraic sum of the voltages across the three elements is greater than the supplied voltages?

Can the voltage drop across the inductor or the capacitor in a seris LCR-circuit be greater than the applied voltage of the a.c. source? Jusitfy your answer.

Figure shows a series LCR circuit connected to a variable frequency 230 V source. L = 5.0 H, C = 80 muF , R= 40 Omega . Determine the rms potential drops across the three elements of the circuit. Show that the potential drop across the LC combination is zero at the resonating frequency. :

In the given circuit, calculate jpotential difference across each element.

When are the voltage and current in LCR circuit in LCR- circuit in same phase?

An alternating voltage of frequency f is applied across LCR circuit. Let f_r be the resonance frequency for the circuit. Will the current in the circuit lag, lead or remain in phase with the applied voltage when f>f_r ? Explain your answer in each case.
