Circuit breaker or fuse.

Electronic devices use all sorts of complicated electronic circuits - amplifier circuits for example, and switching circuits. The details, however, are a bit complicated for a short answer.
Parallel for main circuits and series parallel for lighting circuits.

Electric current in homes is typically supplied by the power grid and enters through the electrical wiring. The current flows through circuits to power electrical devices such as lights, appliances, and electronic devices. It is important to use proper wiring and circuit protection to ensure safety and prevent electrical hazards.

Electricity appears in various forms such as lightning in the atmosphere, electrical circuits in homes and buildings, as well as in electronic devices like phones and computers. It plays a fundamental role in powering modern technologies and infrastructures.

Merlin Gerin is a brand of circuit breaker. This type of unit is used in homes and office buildings as a way to protect electric circuit from causing damage due to short circuits or overloads.
In most cases in Britain there was no way to protect homes.
Overloading of electric circuit means that the current circulating in the circuit becomes more than the capacity of components in the circuit to withstand the current. All components in the circuits have some resistance passage of electricity through this resistance produces heat which is directly proportional to the square of current flowing. The components are designed to withstand only that much of heat as is generated by maximum designed current. When the current is more than this level, or in other words when the circuit is overloaded the components get overheated, leading to their damage. Frequently electric circuits in homes, factories, and other electrical installations incorporate fuses, which are essentially circuit component which protect other components in the circuit by quickly melting or burning out when the circuit is overloaded, resulting in breaking of the circuit. In common language this is called blowing of fuse.
