What type of circuit connects multiple loads to the same power source?

A parallel circuit connects multiple loads to the same power source in such a way that each load operates independently. When loads are connected in parallel, each load receives the same voltage from the power source. This characteristic allows each device to function separately; if one load fails or is removed, it does not affect the operation of the others.

In contrast, a series circuit connects loads in a single path, meaning that the current flows through each load one after the other. In this setup, if one load fails, the entire circuit is interrupted, causing all loads to stop functioning.

Combined circuits typically refer to configurations that include both series and parallel connections, but they do not exclusively connect multiple loads to the same power source in a way that ensures independent operation. Complex circuits may involve various arrangements, including series and parallel elements, but the term does not specifically indicate that multiple loads share the same power source as in a parallel circuit.

Thus, the defining feature of a parallel circuit, where multiple loads can simultaneously operate without being affected by the performance of the others, makes it the correct choice for the given question.
