Question 19Electricity & Electronics - QMED

The correct answer is A) an open circuit. When a fuse blows, it creates an interruption or break in the electrical circuit, effectively creating an open circuit. This means that the flow of electrical current is stopped, and no current can pass through the circuit. The other options are incorrect because: B) A bonded circuit refers to a connection between two conductive parts, not a blown fuse. C) A grounded circuit has a direct connection to the ground, which is not the case with a blown fuse. D) A short circuit is a condition where current flows through an unintended path, bypassing the load, which is not the case with a blown fuse.
