What type of circuit has two or more components connected such that there is only one path for current flow?

A circuit that has two or more components connected in such a way that there is only one path for current flow is known as a series circuit. In a series circuit, the components are arranged one after another, meaning that the electric current flows through each component sequentially. If any component in the series circuit fails or is disconnected, the entire circuit opens, preventing current from flowing through the circuit.

This configuration results in the same current flowing through all components, which is an essential feature of series circuits. The voltage across each component can vary, but the total voltage of the power source is equal to the sum of the voltages across each component. This distinct characteristic makes series circuits useful in various applications where the same current is needed for each component, such as in string lights or in certain battery configurations.
