Transformer.

Microphone.

Plz mark me as the brainliest.

Answer 2

The four devices that work on the principle of the moment are:

• See-saw
• Beam balance
• Transformer
• Microphone

The principle of the moment states that if the body is balanced the total clockwise moment about a point is equal to the total anticlockwise moment on the same point.

Mathematically,

    Moment= Force(F) × Perpendicular distance from the pivot(d)

    Moment= F×d
