प्रश्न
Why fuse wire must always be connected in ‘live’ wire? Explain.
उत्तर
Under any circumstances, fuse wire always be connected in a live wire and never in neutal wire. The reason is that in the case of over-loading, if fuse wire is connected in neutral wire, it will certainly melt and break, but the electric appliance still be in contact with the live wire, so if any person happens to touch the appliance, he will get a shock which may prove fatal.
