Question

The wires connecting the cell and the bulb create a closed circuit. what would happen if one of these wires were cut?

a) The wire would become hot.
b) The bulb would not glow.
c) The bulb would burst.
d) The cell would lose its charge.

Answer 1

The bulb lights up very suddenly as the circuit is closed. The situation changes from equilibrium, where there is very little happening to a steady-state, where the bulb is shining quickly. When the circuit is incomplete, then the current will not flow and loses its charge.

Complete step-by-step solution:
When more electrical devices display in a circuit with a power source, there are many essential means to join them. They can be joined in series or connected in parallel. If combined in series, they are joined so that a separate charge would move through each one of the light bulbs continuously. When in series, the charge crosses through every light bulb. The light bulbs are located within a separate section line, and a charge crossing the external circuit will move through only one of the branches through its path back to the low potential end. The resistors connected will significantly affect the overall resistance of the circuit, the whole current in the circuit, and the current in all resistors.
A conclusion that is unique to series circuits is the consequence of transferring a bulb from a socket. If the current is split from any one of them, it is split from all of them. Very obviously, the appliances in the kitchen are not joined in series.

The wires connecting the cell and the bulb create a closed circuit, if one of these wires were cut then the circuit will discontinuous, the cell would lose its charge.
Option (d) is correct.

Note: In series, for the devices in a line circuit to operate, each device must run. If one runs out, they all go out. Assume that all the devices in a household mess were all joined in series. For the fridge to work in that kitchen, the dishwasher, the toaster oven, garbage disposal, and hanging light would all be on. Inline for one device in series to operate, they all must run.
