difference between DC Motor and AC Generator
Answers
Answer:
A.C Generator
The value of the voltage generated in A.C. generator depends on the number of turns in the coil that is placed in the magnetic field, strength of the magnetic field of the magnet, and the speed of the rotation of coil in field. In A.C. generator, the coil is rotated in the magnetic field of a magnet and it produces current.
D.C. Motor
In D.C. motor, current is provided to the coil and it rotates in the magnetic field. This rotation is used in doing some work. Torque of coil is increased if the current or magnetic field is increased.
A.C. Generator vs. D.C. Motor
Construction:
A.C. generator consists of a coil that is connected to slip rings.
D.C. motor consists of a coil that is connected to split rings.
Battery:
In A.C. generator, the coil is not connected to a battery.
In D.C. motor, the coil is connected to a battery.
Galvanometer:
A galvanometer is connected to the wires of A.C. generator.
A galvanometer is not used in D.C. motor.
Commutator:
A split ring commutator is not used in A.C. generator.
A split ring is connected in a D.C. motor.
Working Principle:
Working principle of A.C generator is electromagnetic induction.
D.C. motor works on the principle of torque/rotation.
Function:
A.C. generator converts mechanical energy into electrical form of energy.
D.C. motor converts electrical energy into mechanical form of energy.
Uses:
A.C. generator is used in countries which suffer from load-shedding. People use it as an alternative to electricity.
Answer:
Explanation: A DC motor is a device which converts machenical energy into electric energy.
AC generator : It is a device that produces a potential difference. A simple AC generator consist of a coil or wire rotating in a magnetic field cars use a type of AC generator called an alternater to keep the battery charged and to run the electrical system while the engine is working.
The alternating current produced in India has a frequency of 50 Hz.
