what is dynamo? write its one use?
Answers
A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a mechanical commutator. Also, converting alternating to direct current using power rectification devices (such as vacuum tubes or more recently via solid state technology) is effective and usually economical.
USES:-
~~Hand cranked dynamos are used in clockwork radios, hand powered flashlights, mobile phone chargers, and other human powered equipment to recharge batteries.
⭕Dynamo is a a.c. generater.
⭕It works on A.C. current.
⭕It is used to produce electricity.
⭕AC Generator or Dynamo:-An electric generator converts mechanical energy into electrical energy. The generation of alternating currents (ac) is based on the phenomenon of electromagnetic induction.
