Explanation / Answer

14)
When it is at position a for a long time, The Capacitor will be fully charged and Voltage across the Capacitor = Vb.


A) In the instant after the switch is thrown, the voltage across the capacitor is zero. = False. (It is Vb)
B) In the instant after the switch is thrown the current through the capapacitor is zero.= False. (Capacitor wil have Voltage across it, Vb and it will start discharging).
C) In the instant after the switch is thrown the voltage across the resistor is zero. = False, ( The Capacotor will start discharging via Resistor, so there will be current flowing in the circut and there will be potential across the resistor.)
D) The current through the resistor equals the current through the capacitor at all times. = True. ( Same current will flow in the circut.)
