2. The following series circuit (with a battery, switch, resistor in series with a capacitor, and an ammeter) is set up. C = 800F
R = 1k ohms
V = 8V

(a) Calculate the maximum initial charging current when the switch is
closed.
(3)
(b) When the voltage across the capacitor is 3 V, calculate what the
reading on the ammeter will be (4)
(c) If R is replaced with a 2 k ohms resistor, what effect will this have on
the maximum current?
(1)
(d) How does this change affect the time taken to charge up the
capacitor?
