Why are AC generators preferred over DC generators?

High voltages AC generators are much simpler and cheaper than DC generators of the same range. When voltages is stepped up current decreases to a small value. Small current produces less heat and can be transmitted through a thin conductor. Thus it is possible to transmit AC at high voltages.

Why are DC generators used?

They are used for general lighting. They are used to charge battery because they can be made to give constant output voltage. They are used for giving the excitation to the alternators. They are also used for small power supply (such as a portable generator).

What is the most appropriate reason for the popularity of AC over DC A AC is not continuous?

Physical Science (c) option is correct. Because of little lose of energy in AC transmission.

What is the advantage of alternating current generator?

Advantages of ac generators : AC is very easy and efficient to transmit over a long distance rather than DC. The design of the AC generator is fairly simpler than DC generator type. No need for matching a voltage. Cost of ownership is lower.

What is the basic difference between an AC generator and a DC generator 1?

So, we can say that the essential difference between an AC generator and the DC generator is that an AC generator has slip rings while a DC generator has commutators. So, the correct answer is “Option D”.

Where do we use DC generator?

Applications of DC Generators They are used in DC motors where speed control is necessary. They are used as portable generators where low power supply is required. They are used in motorcycles as dynamos, in toys such as remote control cars and in appliances such as electric shavers.

How does the DC generator work?

A DC generator operates on the principle of Faraday’s laws of electromagnetic induction. According to Faraday’s law, whenever a conductor is placed in a fluctuating magnetic field (or when a conductor is moved in a magnetic field) an EMF is induced in the conductor.

What are the advantages and disadvantages of AC and DC?

(i) The generation of AC is cheaper than that of DC. (ii) When AC is supplied at higher voltages, the transmission losses are small compared to DC transmission. (iii) AC can easily be converted into DC with the help of rectifiers.

What is the difference between AC generator and DC generator?

While DC generators are mainly used to supply power for large motors, AC generators are used for smaller ones. You can power your electrical appliances at home with the help of AC like food mixers, electrical fixtures, etc. The Diff BW AC and DC Generator in terms of maintenance are huge.

What are the different types of generators?

Based on the attained output, this electrical generator can be classified into two types namely AC generator and DC generator. This article discusses the main difference between AC and DC generators.

How does an AC generator generate electricity?

The AC or DC generators apply the same principle to generate electric current. However, there are two ways to vary the magnetic field acting on the conductors. Either rotate the magnetic field around a stationary conductor or spin the conductor inside a stationary magnetic field.

What are the commutators in an AC generator?

There are no commutators in AC generator. It has commutators to supply unidirectional current. It uses a slip ring to transfer the induced current smoothly to the circuit. It uses split rings to transfer the induced current to the circuit & also convert the induce AC into pulsating DC. The generated output voltage amplitude is relatively higher.
