# What are some examples of series and parallel circuits in our daily life?

If a single switch controls many lights, they are connected in parallel. The electrical circuits present in houses and automobiles are the most frequent daily series circuits, with the distinction being the type of voltage employed in each. Series circuits require one power source to be connected up front while multiple units can be plugged into a wall outlet using different sets of cables for each light. Parallel circuits are just the opposite: several lights can be connected up front with one power source.

In electronics, a series circuit is a circuit in which all the components receive electricity from one another but not from the main power supply. For example, if eight light bulbs are wired in series, then each bulb receives current from the next, without having to be connected to the main power line. This is what happens when you plug a lamp into a cigarette lighter or auxiliary socket on a car dashboard. The term "series connection" also refers to any one of these situations.

A parallel circuit is a circuit in which all the components receive electricity from the main power supply. For example, if eight light bulbs are wired in parallel, then each bulb would need its own power cord to be plugged into an electric wall socket. This is how house wiring works; each room has wires running to each light fixture, fan, heater, etc. To save money, these individual pieces of equipment are usually shared by more than one room.

## What are examples of series and parallel circuits?

The circuit on the right shows how to employ both series and parallel connections inside the same circuit. In this scenario, light bulbs A and B are linked in parallel, whereas light bulbs C and D are connected in series. This is an illustration of a combo circuit. A combo circuit has two or more branches that can be used to connect one lamp to a power source.

The connection between two lamps inside a branch of a combo circuit is called a branch point. At this branch point, either the input from one lamp's filament will be sent to the other lamp or both filaments will be connected to the power source. If the branch points for two or more lamps are not taken into account when designing the combo circuit, then these lamps will not work properly. For example, if you were to connect four 5-watt lamps in series without considering the combination of their leads at the ends of the chain, then only two watts of power would reach the last lamp in the series string. This is because they could not be connected anymore after the first two.

Lamps that are wired in parallel carry full load currents but only share the power supply voltage. Parallel-wired lamps should be of like size and type (e.g., fluorescent tubes). They should also be mounted in close proximity to each other. An open space between them might cause one bulb to burn out before all its companions.

## Which circuit series or parallel is the brightest?

Bulbs connected in series are brighter than bulbs connected in parallel. The voltage for each bulb in a parallel circuit is the same as the voltage in the circuit. The unscrewing of one bulb has no effect on the other. In contrast, if all the bulbs in a series circuit were to be removed at once, it would cause an open circuit condition which would require additional current from another source in order to maintain electricity flow.

Because more electricity is needed when less light is produced, series circuits require more electrical power to operate them than parallel circuits. A rule of thumb is that series circuits need about 30% more electrical power than parallel circuits of equal size parts. This is because the total amount of electricity used by series circuits is the sum of the amounts used by each part, while with parallel circuits there's only as much electricity used as there are parts in the circuit.

For example, if you have a series circuit of four lamps and want them to emit the same amount of light they would if they were all operating in parallel, you would need to connect two lamps together in parallel with each remaining lamp in the series connection.

This is why regular household lights are usually designed to be used in parallel rather than in series.
