An electric iron requires a ________ fuse to prevent short-circuiting.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 5 A.
An electric iron typically requires a 5 A fuse to prevent short-circuiting. The fuse is designed to handle the higher current demand of the electric iron, as it typically operates at a power range of 1000-2000 watts, which requires more current. A 5 A fuse ensures that if there is any electrical fault, such as a short circuit or overload, the fuse will blow, thereby protecting the appliance and preventing any damage or potential hazards like fires or electric shocks.
