In a parallel circuit, how are the components connected?

In a parallel circuit, components are connected in separate loops, allowing each one to have its own direct path to the power source. This configuration means that if one component fails or is removed, the other components in the circuit can continue to function normally. Each branch in a parallel circuit allows for independent operation of devices, maintaining the voltage across each component the same as the supply voltage. This setup is particularly useful in household wiring, where you can have multiple devices powered independently without them all needing to be in the same continuous loop.

The other arrangements do not reflect the nature of a parallel circuit; a continuous loop describes a series circuit, while a single line implies there's only one direct path for current to flow, which would again suggest a series connection. The mention of a star formation does not adequately describe how components are connected in standard parallel configurations.
