5. Function of a switch is to interrupt the current delivered to the load by the source.
6. A short circuit occurs when there is a drop in the resistance or a broken insulation.
7. To prevent short circuits we can use fuses.
8. A fuse melts when too much current flows through them, interrupting in this way the circuit.
