(b) One of the lamps in the set is a fuse lamp. This contains a filament which melts if a fault occurs. A short time after the lights are switched on, a fault causes the filament inside the fuse lamp to melt and all the lamps go out. The householder cannot find another fuse lamp so connects a piece of aluminium foil across the contacts inside the fuse lamp holder. When switched on, the nineteen remaining lamps work. What the householder has done is dangerous. Explain why.
