In an LCR circuit both switches
are open initially. Now switch S1 is closed S2 kept
open. (q is charge on the capacitor and τ = RC is
Capacitive time constant). Which of the following
statement is correct ?
(1) At t = 2τ, q = CV (1 – e–2)
(2) At t =
2
τ , q = CV (1 – e–1)
(3) Work done by the battery is half of the energy
dissipated in the resistor
(4) At t = τ, q = CV/2
