Charge on a capacitor is expressed as Q = CV
Expression of voltage across the capacitor is:
Since the time constant τ is given as, τ = RC
The switch in the figure has been in position a for a long time. It is changed to position b at t = 0 s.
A. What is the charge Q on the capacitor immediately after the switch is closed?
B. What is the current I through the resistors immediately after the switch is closed?
