Question

how are bulbs connected in series ? what is its defect ?

Answer 1

hi here is ur answer >>↓↓<<

Energy is divided among more lamps so the voltage drops across each lamp. In the parallel circuit, all lamps get the same voltage, so all are the same brightness. ... To prevent overloading in circuits, fuses are connected in series along the supply line. In this way the entire line current flows through the fuse.

hope it helps ^_^
