Question

three point of AC generator differ from DC generator

Answer 1

Answer:

Ac currents will produce attractive currents

while dc currents will produce repulsive current....

Answer 2

Explanation:

In an AC generator, the electrical current reverses direction periodically. In a DC generator, the electrical current flows only in one direction. In an AC generator, the coil through which the current flows is fixed while the magnet moves. ... DC generators have commutators to make the current flow in one direction only.

AC Generator

1

Definition

AC generator is a mechanical device which converts mechanical energy into AC electrical power.

DC generator is a mechanical device which converts mechanical energy into DC electrical power.

2

Direction of Current

In an AC generator, the electrical current reverses direction periodically.

In a DC generator, the electrical current flows only in one direction.

3

Basic Design

In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less.

In a DC generator, the coil through which the current flows rotates in a fixed field. The overall design is very simple but construction is complex due commutators and slip rings.

4

Commutators

AC generator does not have commutators.

DC generators have commutators to make the current flow in one direction only.

5

Rings

AC generators have slip-rings.
