Is a generator AC or DC current?
Machines that convert mechanical energy into electrical energy are termed as generators. Generators are of two types alternating current and direct current generators.
What type of current is a generator?
alternating current
AC and DC power generators both use electromagnetic induction to generate electricity. However, the process they use is different. An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction.
Is DC generator a source of direct current?
In direct current, the current flows in one direction only. Some sources of direct current are cell, DC generator, etc. Dry cell, dry cell battery, car battery and DC generator, radio and television works only with D.C they have a device in them which convert A.C supplied to them into D.C.
Can you generate a DC current?
Generating DC 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.
Where is DC generator used?
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.
Is an example of DC source?
Direct Current Circuits Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type.
Which is the principle of DC generator?
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.
