Q)

Read the passage carefully and answer the question given below <br><br> Electric fuse: <br> It is a safety device used to protect electrical appliances from strong currents. A fuse wire must have high resistivity and low melting point. It is usually made from an alloy of tin and lead. It is put in series with the live wire of the circuit. The electric installations are thus saved from getting damaged. <br><br> Thus fuses used for domestic purpose are rated 1A, 2A, 3A, 5A, 10A, etc. For an electric iron that consumes 1KW electric power when operated at 220V, a current of (1000/220) A that is 4.54A will flow in the circuit. In this case a 5A fuse must be used. <br><br> Question : A toaster is marked 1500W/220V. What should be the rating to fuse used across this appliance

$\begin{array}{1 1} (a)\; 4A \\ (b)\; 5A \\ (c)\; 10A \\ (d)\; 13A \end{array}$
