AC generator produces AC current, whereas DC generator produces DC current.

in AC generator slip rings are present, whereas in DC generator split rings are present.

AC Generator vs DC Generator

AC Generator:
- An AC generator, also known as an alternator, produces alternating current (AC) electricity.
- In an AC generator, the coil rotates within a magnetic field, inducing an alternating current in the coil.
- AC generators are commonly used in households and industries to provide power for appliances and machinery.
- The voltage produced by an AC generator can be easily changed using a transformer.

DC Generator:
- A DC generator produces direct current (DC) electricity.
- In a DC generator, the coil rotates within a magnetic field, generating a direct current in the coil.
- DC generators are often used in applications where a constant and steady source of power is required, such as in battery charging systems.
- The voltage produced by a DC generator remains constant unless manually adjusted.

Main Differences:
- AC generators produce alternating current, while DC generators produce direct current.
- AC generators are commonly used in households and industries, while DC generators are used in applications requiring a constant power supply.
- AC generators can easily change the voltage using a transformer, while the voltage produced by DC generators remains constant.

In summary, the key difference between AC and DC generators lies in the type of electricity they produce and their applications. AC generators are suitable for general power supply purposes, while DC generators are more suitable for applications requiring a constant and steady power supply.
