The radio tuning capacitor consists of 26 plates of area 24 cm^2. The distance between plates when set for maximum capacitance is 2mm.
Assuming that the area of projection at maximum capacity is equal to the area of the plates, find the maximum capacity of this condenser.
Capacitors of 2μF and 6μF are connected to a 100V battery. How much charge I supplied by the battery in charging the capacitors when (a) they are connected in series and (b) when they are connected in parallel?
