what is the basic difference between ac and dc generator?

An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction. In an AC generator, the coil through which current flows is fixed and the magnet usually moves.

A C Motor works on the concept of alternating current, whereas DC Motor works of the Direct Current. ... DC Motor are self-starting motors. The Armature is stationary, and the magnetic field rotates in the AC Motor but in DC Motor the armature rotates, and the magnetic field is stationary.

Why, Alternating Current and Direct Current, of course! Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically.

Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. ... Most of the digital electronics that you build will use DC.

Alternating current is cheaper to generate and has fewer energy losses than direct current when transmitting electricity over long distances. Although for very long distances (more than 1000 km), direct current can often be better.

In a so-called 'DC generator', this AC current is generated in the rotating armature, and then converted to DC by the commutator and brushes. In an 'alternator', the AC current is generated in the stationary stator, and then is converted to DC by the rectifiers (diodes).

In an AC generator, the coil through which current flows is fixed and the magnet usually moves. The south and north poles of the magnet make the current flow in opposite directions, thereby creating an alternating current. In contrast, the coil in a DC generator is not fixed; rather it rotates in a fixed field.

AC induction motors use a series of coils powered and controlled by AC input voltage. ... Consequently, AC motors are less efficient than DC motors. In fact, the DC motor is 30% more efficient than AC motors due to the secondary magnetic field being generated from the permanent magnets rather than copper windings.

An alternator is a device that converts mechanical energy into AC electrical energy. A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy. An alternator always induces an alternating current. A generator can generate either alternating or direct current.

Both AC (Alternating Current) and DC motors have the same basic structure but there are differences and, for various reasons, the DC motor was originally the preferred form of motor for railway applications and most systems used it.

AC vs DC (We only sell AC Ballasts): Both types of ballasts take the DC power from vehicles and power the HID bulbs for light. The difference in these ballasts is in the type of electricity being outputted to the HID bulb. AC ballasts output AC power, while DC ballasts output DC power.

An amplifier is used to increase the strength of an electric signal whereas a rectifier allow current to pass in only one direction and is used to produce DC. from AC.

An alternator is a device that converts mechanical energy into AC electrical energy. A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy. ... Alternators have higher output than generators. Generators have a lower output when compared with an alternator.

Difference Between AC & DC Bridge. One of the significant difference between the AC and DC bridge is that the AC bridge is used for measuring the unknown impedance of the circuit whereas the DC bridge is used for measuring the unknown resistance of the circuit.

The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy. The generator is vice versa of that motor. It converts mechanical energy into electrical energy.

DC can be generated in a number of ways: An AC generator equipped with a device called a "commutator" can produce direct current. Use of a device called a "rectifier" that converts AC to DC. Batteries provide DC, which is generated from a chemical reaction inside of the battery.
