Q1. Given below are two statements: Statement I: The fuse is placed in parallel with the device in the circuit. Statement II: The fuse used in the electric circuit protects the appliances by allowing the flow of high current through them. In light of the above statements, choose the most appropriate answer from the options given below.
Explanation
A fuse is connected in series with the appliance, not in parallel, so that the entire circuit current passes through it. If the current exceeds the safe limit, the fuse wire melts and breaks the circuit. It protects appliances by stopping excessive current, not by allowing high current to flow through them. Therefore, the statement about parallel placement is wrong, and the statement about protection through high-current flow is also wrong. The only correct judgement is that both statements are incorrect.
