What is a series connection?

A series connection is an electrical connection where the components are connected one after the other in a single circuit. In a series connection, the current flows through each component, meaning that the same current passes through each component, and the total current in the circuit is the same.

In a series connection, the voltage is added across the components, so that the total voltage across the entire circuit is the sum of all the voltages. Series connections are commonly used in Christmas lights, filaments in a light bulb, and in other types of circuits where a sequential passage of current through multiple components is necessary.

What is the difference between series and parallel connection?

In a series connection, cutting off the power supply can be done at multiple points by turning off one switch, such as when unplugging the cord connected to the Christmas lights. In contrast, a parallel connection is associated with only one connection, such as when turning off a light switch, only one light goes out.
