write the working principle of generator
Answers
Answer:
electromagnetic induction
Generator is an instrument based on the principle of electromagnetic induction which produces electric current using mechanical energy.
Working of Generator :-
We know, When a magnet is moved back & forth inside a coil, it produces electric current.
A rectangular copper coil is rotated in the influence of magnetic field which is connected to the two ends of circuit using commutator and carbon brush and split rings.
When the coil is rotated, At the first hand the direction of force would be upwards while the direction of magnetic field would be from North to south, So using Fleming's right hand rule we can find the direction of electric current. Because of the split rings the direction of electric changes at some interval. So, This type of generators are called AC generator.
Principle Of Generator :-
Generators are based on the principle of electromagnetic induction which states that when a magnet is moved back and forth inside a coil or loop, It produces electric current in the coil.
