What is Series circuit

A series circuit is a type of electrical circuit where the components or devices are connected in a continuous row, forming a single path for the current to flow. In this configuration, the current passes through each component in sequence, one after the other. The current remains constant throughout the entire circuit. This means that the current flowing through each component is equal.

In a series circuit, the voltage is divided among the components based on their resistance or impedance. The total voltage of the circuit is equal to the sum of the voltage drops across each component. If one component fails or is disconnected, the entire circuit is interrupted, as the current can only flow in one path. This results in all devices or components connected in a series circuit ceasing to function simultaneously if one of them fails.

Series circuits are commonly used in the lighting industry, particularly in the arrangement of lights such as strings of Christmas lights or landscape luminaries. However, they are not frequently used in house wiring due to their drawbacks. Troubleshooting and repairing series circuits can be inconvenient and time-consuming, as the failure of one component affects the entire circuit. Additionally, the voltage drop across each component in a series circuit can lead to reduced brightness or performance for devices further down the circuit.
