How many paths for current flow does a series circuit contain?

In a series circuit, there is only one single path for current flow. This characteristic means that the electrical components (such as resistors, capacitors, and inductors) are connected end-to-end, forming a single pathway through which the current must travel. As a result, if any component in the series circuit fails or is disconnected, the entire circuit becomes open, and no current can flow.

This simplicity of having one path also means that the total resistance of the circuit is the sum of the individual resistances of all components. In practical applications, understanding that there is only one path for current flow is crucial for troubleshooting, circuit design, and predicting how changes in the circuit will affect the overall operation.
