Question

In an electric circuit, the device used to prevent damage to the electrical appliances due to overloading is:

• A. electromagnet
• B. electric fuse
• C. battery
• D. electric cell

Hint:

A fuse is a safety device that protects circuits from overcurrent.

Answer 1

The Correct Option is B

Step 1: Understand the problem of overloading in electric circuits.
Overloading occurs when the current in a circuit exceeds its safe limit. Step 2: Recall the function of each device listed.
Electromagnet: Produces a magnetic field using electric current.
Electric fuse: A safety device that breaks the circuit if the current is too high.
Battery: A source of electrical energy.
Electric cell: A single unit that converts chemical energy to electrical energy.
Step 3: Identify the device designed for overload protection.
The electric fuse is designed to melt and break the circuit when an overload occurs, thus preventing damage to appliances.
