In given circuit capacitor initially uncharged. Now at t=0 switch S is closed then current given by source at any time t is

\[\frac{\varepsilon }{2R}\left( 1+{{e}^{\frac{-2t}{CR}}} \right)\]

[frac2Rleft( 1-e^frac-2tCR right)]

[fracvarepsilon 2Rleft( 1-e^frac-2tCR right)]

[frac2varepsilon Rleft( 1-e^frac-2tCR right)]

What is the value of inductance L for which the current is maximum in a series LCR circuit with [C=10mu F] and [omega =1000s^-1]?

cannot be calculated unless R is known

Over a fall cycle the capacitor C does not consume any energy from the voltage source.

Current I (t) lags voltage V (t) by [90^circ ].

Current I (t) is in phase with voltage V (t).

Current I (t) leads voltage V (t) by [180^circ ].

\[\frac{{{10}^{2}}(10-{{\pi }^{2}})}{\pi }\,\Omega \]

\[45{}^\circ ,\text{ }0.5\text{ }A\]
