The positive terminal of a voltage source (v=12v ) is connected to a capacitor c1 = 4 μf. this capacitor is then connected to a parallel connection of two capacitors, c2 = 3μf and c3 = 2μf. from this parallel connection the wire leads straight back to the negativ terminal of the voltage source. what is the charge on capacitor c2?

When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(ii) sulfate is reduced to lead at the cathode and oxidized to solid lead(ii) oxide at the anode. suppose a current of is fed into a car battery for seconds. calculate the mass of lead deposited on the cathode of the battery.
