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 Capacitance time constant). Which of the following statement is correct ? JEE Main 2013 (Offline) Physics - Alternating Current Question 155 English

Multiple Choice Options

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

Step-by-Step Verified Solution

Charge on he capacitor at any time t is given by

q=CV(1−et/τ)

at t=2τ

q=CV(1−e−2)
