From the figure beside, the switch has been closed for long time. Calculate: a) The steady current in each branch. b) The charge on the capacitor. If the switch is opened; calculate; c) The current in R2 as a function of time. d) The time interval required for the energy stored in the capacitor to be / its maximum value. e) The time interval for the voltage to be 0.37 its maximum value 12.0 10 9.00V
