Directions: In the following questions, a statement of assertion (A) ...
Safety fuses are made up of materials having a low melting point so that when excess current flows through the circuit, the fuse melts breaking the circuit and thus prevents appliances.

Directions: In the following questions, a statement of assertion (A) ...
Assertion: Safety fuses are made up of materials having a low melting point.
Reason: Safety fuses should be resistant to electric current.
The correct answer is option E, which states that both the assertion and reason are false.
Explanation:
Reasoning for Assertion:
Safety fuses are designed to protect electrical circuits from overloading or short-circuiting. When an electrical circuit experiences an overload or a short circuit, the current passing through the circuit increases significantly. The safety fuse is designed to break the circuit and prevent any further flow of current, thereby protecting the circuit and preventing potential damage or hazards.
Reasoning for Reason:
The reason given for the assertion is incorrect. Safety fuses are not required to be resistant to electric current. In fact, safety fuses are designed to melt when the current passing through them exceeds a certain limit. This is achieved by using materials with a low melting point. When the current exceeds the rated value, the fuse wire melts and breaks the circuit, preventing any further flow of current.
Explanation:
The assertion states that safety fuses are made up of materials having a low melting point. This is true because safety fuses are designed to melt when the current exceeds a certain limit. This is achieved by using materials such as tin, lead, or alloys that have low melting points. When the current exceeds the rated value, the fuse wire melts and breaks the circuit, preventing any further flow of current and protecting the circuit from damage.
However, the reason given for the assertion is incorrect. Safety fuses are not required to be resistant to electric current. In fact, safety fuses are designed to melt when the current exceeds a certain limit. The purpose of a safety fuse is to break the circuit and prevent any further flow of current in order to protect the circuit from damage or hazards. Therefore, the reason provided does not correctly explain the assertion.
Hence, both the assertion and reason are false, and option E is the correct answer.
