Describe what happens during an open circuit.

In an open circuit, the electrical path is compromised, preventing the flow of current. This occurs when there is a break in the circuit, such as a disconnected wire or a switch being in the 'off' position. Because the circuit is not closed, the electrons cannot complete the circuit, which means no electrical current will pass through the components in that circuit.

This condition is essential to understand in electrical systems because it highlights how circuits must be completed for devices to operate. Without this completed path, any devices connected will remain inactive, providing a practical safety mechanism as well. This concept establishes foundational knowledge for troubleshooting and designing electrical systems effectively.
