Answer the following questions:
Graph of emf and current versus time
(a)[3.0]
The continuous graph below shows variation of emf versus time when applied to a component X. The dotted line graph is that of current versus time.
(1) Identify the component X.
(2) Calculate the root mean square value of the current ($I_{\text{rms}}$) flowing in the circuit.
(3) Calculate the value of the opposition (in ohm) offered by the component X to the flow of current through it.
(b)[2.0]
Obtain an expression for the resonant frequency ($f_{0}$) for a series LCR circuit.
