a. 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= 60000000 ohm the capacitor has capacitance C= 3e-06 Farads and the battery maintains the emf of E= 18 V. The switch is closed to a at time t=0s and the capacitor begins to charge. What is the time constant for this circuit?

b. What is the voltage across the resistor after the switch has been closed for t=15 s?

c. What is the current through the circuit after the switch has been closed for t=15 s?

d. What is the voltage across the capacitor after the switch has been closed for t=15 s?

e. What is the charge on the capacitor after the switch has been closed for t=15 s?
