Question

An electric iron is rated 1 kW and the voltage supplied is 240 V. What is the resistance of the heater? What is the rating of a suitable fuse for this equipment to safeguard it from overloading ?

Answer 1

The rating of the fuse depends on the current flowing $I=\frac{V}{R}=\frac{240}{1\ast {10}^3}=0.024A$

therefore it is suitable for $0.024A$
