Marks: +1, -0

In an LCR circuit as shown below 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?

[Main 2013]

At t=τ,q=CV/2
At t=2τ,q=CV(1−e−2)
At t=
τ
2
,q=CV(1−e−1)
Work done by the battery is half of the energy dissipated in the resistor.
