An uncharged capacitor of 30 µF, a 35 ohm resistor, a battery and an open switch are connected in series. This battery has a potential difference of 50 volts between its terminals before supplying current to the circuit. The cables connecting the battery and circuit elements have no remarkable resistance. At t = 0, the switch is closed suddenly.

a) What is the largest current value passing through a resistance of 35 ohms and when does it reach this value?
b) What is the largest load value that the capacitor will charge?
c) What is the amount of charge on the capacitor's boards when the current reaches 0,85 A in the circuit?
