What happens to a circuit when current flow is interrupted by a blown fuse?

When a blown fuse interrupts the flow of current in a circuit, it creates an open circuit. A fuse is designed to protect the circuit by breaking the connection if the current exceeds a certain limit, thereby preventing damage from overheating or overloading. When the fuse blows, the continuity of the circuit is broken, which stops the flow of electricity.

An open circuit is characterized by a break in the conductive path, meaning that no current can flow. This is essential for safety and the protection of electrical devices and components connected to the circuit. By stopping the current flow, an open circuit ensures that downstream devices are not exposed to excessive current, preventing potential damage.
