Electrical circuit diagram with battery, resistor, three light bulbs, and three switches.

Two cells are connected positive to negative to form a series power source. • From the positive terminal, current flows to a fuse for protection. • After the fuse, the circuit splits into three branches: • Each branch has: • One light bulb • One switch in series with that bulb • All branches reconnect and flow back to the negative terminal of the battery.
