A fuse rated at 3 A is connected in a circuit. If a current of 5 A flows through the circuit, what will happen to the fuse and why?
- The fuse wire melts and opens the circuit because the current is too high.
- The fuse wire becomes thicker to allow more current to pass.
- Nothing happens because fuses only react to voltage changes.
- The fuse makes the current increase further to protect the circuit.
