An electric iron is marked "1000 W–230 V" and is to be protected by a fuse.
(a) Calculate the steady current drawn by the iron when connected to the 230 V domestic supply.
(b) The available cartridge fuses are rated 3 A and 5 A. Identify which one should be fitted for safe operation of the iron and justify your choice with calculation.
(c) Explain qualitatively what would happen if the other fuse rating were used instead.
