A 2KW AC is to be used on a 250 V AC mains for which a 3-pin top plug fitted to a cable is required. Which of the following options is NOT correct:

Correct option is D

The correct answer is (D) the appropriate value of fuse to be used is 12A.

The statement "the appropriate value of fuse to be used is 12A" is not correct. The correct fuse rating for a 2 kW AC appliance is usually 15 A. 

Explanation

• A fuse is a safety device that is connected to the live wire of a mains electric supply. 
• The fuse rating should be appropriate for the appliance being used. For example, a 2 kW AC appliance typically requires a 15 A fuse. 
• If the fuse rating is too high, it may not blow when a higher current passes through the cable, which could cause overheating and an electrical fire.
