An Uncharged 30

question 24

Essay

An uncharged 30.0-µF capacitor is connected in series with a 25.0-Ω resistor,a DC battery,and an open switch.The battery has an internal resistance of 10.0 Ω and the open-circuit voltage across its terminals is 50.0 V.The leads have no appreciable resistance.At time t = 0,the switch is suddenly closed.
(a)What is the maximum current through the 25.0-Ω resistor and when does it occur (immediately after closing the switch or after the switch has been closed for a long time)?
(b)What is the maximum charge that the capacitor receives?
(c)When the current in the circuit is 0.850 A,how much charge is on the plates of the capacitor?
