Three resistors of 4Ω, 6Ω, and 12Ω are connected in parallel The combination of these resistors is connected in series to a resistance of 2Ω and then to a battery of e.m.f 6V and negligible internal resistance.
(a) Draw the circuit diagram
(b) Calculate the current in main circuit
(c) Calculate the current in each of the resistors in parallel
