Different Circuits

A device called a(n) keeps too much current from flowing through wires. The fuse prevents wires from heating up and starting a(n) . There is a strip of metal inside a fuse. This strip is a(n) . The resistor will melt if there is too much flowing through the strip. New homes have a circuit or switch to protect circuits. If a dangerously high current flows through the circuit, the opens. A spring holds the switch open, creating a(n) circuit. If there’s a short circuit, the switch will be in the position.
