Fuses are connected in series with the device they protect, Automatic house-heating equipment has a thermostat, electromagnetic coils, and safety cut-outs connected in series with a voltage source etc. Other appliances which uses series circuit include water heaters, well water pump, lamps, freezers and refrigerators.

Similarly, where do we use parallel and series circuits? series with a device, it controls the device, allowing us to switch it on and off. For example, often lawnmowers have two switches in series with each other so that both switches need to be pressed before the mower will turn on. In the lighting circuit all the lamps are connected in parallel.

Besides, why do we use series and parallel circuits?

In a series circuit, the sum of the voltages consumed by each individual resistance is equal to the source voltage. Components connected in parallel are connected along multiple paths so that the current can split up; the same voltage is applied to each component.

What is the difference between series and parallel circuits?

The main difference between series and parallel circuits is that, in series circuits, all components are connected in series so that they all share the same current whereas, in parallel circuits, components are connected in parallel so that they all have the same potential difference between them.
