1.	What is an electric fuse ? What is its role in the electric circuits? Should it be placed on the neutral wire or on the live wire ? Justify your answer .
Answer» Solution :Afuse is safety device consisting of a thin wire MADE of an alloy of tin and lead having a low melting POINT. If high current flows through it due to short circuit or overloading, fuse wire melts and breaks the circuitoff the supply of ELECTRICITY. Thus, the fuse protects the appliances fromgetting damaged, protects the user from electric shock, and prevents thepossibility of fire. Since the live wire carries electricity, a fuse should be placed in the live wireto function properly.NEUTRAL wire is at zero POTENTIAL and does notcarry electricity. If the fuse is connected to the neutral wireand if a short circuit or an overloading occurs, high current continues to flowthrough the live wire and the fuse does not blow off.
