A household appliance is protected by a 6A fuse and is meant to be operated from a constant 240V mains supply.
(i) Determine the resistance that the appliance must present to the mains so that, under normal operation, the fuse does not melt.
(ii) If the mains voltage rises suddenly by 10%, calculate the new current drawn by the appliance.
(iii) Comment, with proper reasoning, on whether the fuse is likely to blow under the increased mains voltage obtained in part (ii).
