What is
i) an electric generator
ii)an AC generator
iii) a DC generator
Answers
Answer:
In electricity generation, a generator is a device that converts motive power into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks
Explanation:
The function of slip rings: Split ring is used in D.C generator circuit whereas slip rings are used in A.C generator circuit.Slip rings connect the rotating armature of a simple a.c. generator to an external circuit by means of carbon brushes B1 and B2.The external circuit (i.e. load) is connected to the other ends of brushes as shown in the figure. The brushes B1 and B2 do not rotate along with the coil and the slip rings.The basic function of slip rings is to provide voltage to the external circuit and to change the direction of the current.
3)Uses of generator: Providing backup energy for emergencies, Powering construction sites, Powering nuclear reactor plants, Providing backup for hospitals and other office buildings.

Answer:
i) In Electric Generater ,a generator is a device that converts motive power into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks.
ii) AC Generater, also known as alternators, is a machine that converts mechanical energy into electrical energy. The generated electrical energy is in the form of an alternating current sinusoidal output waveform. The mechanical energy is usually supplied by steam turbines, gas turbines and combustion engines.
iii) DC Generater, converts mechanical power (ωT) into DC electrical power (EI), whereas, a DC motor converts d.c electrical power into mechanical power.
