Question

when current flow is interrupted by a blown fuse, the circuit becomes a open. b closed. c parallel. d shorted.

Explanation:

A fuse is a safety - device. When it blows, it breaks the circuit path. In an open - circuit, the current flow is interrupted as there is a break in the conducting path. A closed circuit allows current flow, a parallel circuit is a type of circuit configuration, and a shorted circuit has a low - resistance path between two points in the circuit.

Answer:

A. open
