2. Motor
3. Magnet
4. Generator

Answer 1

Correct Answer - Option 1 : Fuse

The correct answer is Fuse.

• An electric fuse is the most important safety device, used for protecting the circuits due to short-circulating or overloading of the circuits.

• A fuse consists of a low-resistance metal or wire that is used to close a circuit.
• A fuse was patented by Thomas Edison in 1890 as part of his electric distribution system.

• The Electric Motor is mainly classified into two types. They are the AC motor and the DC motor.
• The AC motor takes alternating current as an input, whereas the DC motor takes direct current.
• Magnet is capable of producing a magnetic field.
• This Magnetic field is invisible but is responsible for the most notable property of a magnet.
• Electricity generation converts mechanical energy to electricity for transmission and distribution over power lines to domestic, commercial, and industrial customers.
• It is also called a dynamo.
• Generators also produce the electrical power required for automobiles, aircraft, ships, and trains.
