An electric generator is a device that converts mechanical energy into electrical energy through electromagnetic induction.

Working Principle:

Based on Faraday's Law of Electromagnetic Induction: When a conductor moves in a magnetic field, a voltage is induced across the conductor.

Main Components:

• Rotor: Rotating part (armature or field windings)
• Stator: Stationary part with coils
• Field Magnets: Produce magnetic field (permanent or electromagnets)
• Slip Rings & Brushes (AC) / Commutator (DC): Transfer current to external circuit

Types:

Applications:

Power plants, backup power (diesel generators), portable power, renewable energy systems (wind turbines, hydro).
