Difference between AC and DC Generator

On What Factors does the Emf Produced in a Generator depend?

The emf produced depends on the number of armature coil turns, the strength of the magnetic field and the speed of the rotating field.

How can you convert an AC Generator to a DC Generator?

To convert an AC generator to DC, add a split ring commutator. This switches current direction, making it behave like a DC generator. Alternatively, replace the coil with an armature for the same effect.

Where are AC and DC Generators Used?

AC generators are used in our household electrical appliances and small motors like vacuum cleaners, juicers and food mixers. Whereas, direct current generators are used in large power electric motors such as those used in subway systems, steam turbines, etc.

Is Battery AC or DC?

Batteries and electronic devices such as televisions, computers and DVD players operate on DC electricity – once AC current enters a device, it is converted to direct current. A typical battery supplies about 1.5 volts direct current.

Which is better AC or DC Generator?

AC generators are more efficient than DC because the energy loss in alternating current is much less. DCs are less efficient due to sparking and other losses in copper, eddy current, mechanical and hysteresis.

What are the Similarities between AC and DC Generator?

The basic similarities between AC and DC Generator is that both works on the principle of electromagnetic induction i.e. when coil is rotated in the presence of magnetic field then electric current is produced.

An electrical machine that converts mechanical energy input into electrical energy output is called a generator or electrical generator. There are two types of generators, AC Generators and DC Generator. An AC generator has an electromagnet while a DC generator has a permanent magnet. AC generators have commutators while DC generators have slip rings.

In this article, we will learn what is AC and DC Generators and the Difference Between AC and DC Generator. There are some important differences between AC and DC Generator which we will understand below through the difference table but before that let us understand better what is AC and DC Generator.
