Explanation of circuit
It is a parallel circuit with 2 batteries. There are 3 bulbs and 3 switches, each switch controlling each bulb (To off and on whichever bulb needed). If one bulb fuses, the other 2 teams will still have light so too bad for the third team :(.. The current flows from the positive terminal to negative terminal.
