a) What is the time constant for this circuit? 6.1210-3 s b) What is the charge

Question

a) What is the time constant for this circuit? 6.1210-3 s

b) What is the charge on the capacitor after the switch has been closed for t=7.3410-3 seconds?

c) What is the current through the circuit after the switch has been closed for t=7.3410-3 seconds?

d) What is the voltage across the capacitor after the switch has been closed for t= 7.3410-3 seconds ?

I got part A but have no idea how to do part b,c and d

An RC circuit, hooked up to a battery as shown in the figure below, starts with an uncharged capacitor. The resistance in the circuit is R= 360. ? the capacitor has capacitance C= 17.0 ?F and the battery maintains the emf of E= 11.0 V. The switch is closed at time t=0.00s and the capacitor begins to charge. a) What is the time constant for this circuit? 6.12 10^-3 s b) What is the charge on the capacitor after the switch has been closed for t=7.34 10^-3 seconds? c) What is the current through the circuit after the switch has been closed for t=7.34 10^-3 seconds? d) What is the voltage across the capacitor after the switch has been closed for t= 7.34 10^-3 seconds ? I got part A but have no idea how to do part b,c and d

Explanation / Answer

b)

The maximum charge on the capacitor is given by

q0 =CVo =(17*10-6)(11) =187uC

now the charge after t=7.34
