Which type of circuit allows electricity to flow completely?

A closed circuit allows electricity to flow completely because it provides a continuous path for current to travel from the power source, through the circuit components, and back to the power source. This uninterrupted loop is essential for the operation of electrical devices. When a circuit is closed, all components within it function correctly, enabling devices to turn on and perform their intended tasks.

On the other hand, an open circuit contains a break or gap that stops the flow of electricity, which prevents any current from reaching the load. A short circuit, while it allows electricity to flow, occurs through an unintended path that bypasses the load, which can lead to dangerous situations like overheating or damage. A switch circuit generally refers to circuits that can be opened or closed, but the key aspect of a closed circuit is its ability to maintain a complete path for electrical flow, ensuring proper function of electronic devices.
