0Introduction:-
A transformer is the most important electrical instrument , used to trasfer electrical engergy from One circuit to the Other with the help of Magnetic field and without any change in frequency.
Principle :-
It works on Lenz's Law. According to this , an E.M.F is induced in a coil, if the coil links to changing flux.
Mathematically,
where N = No of Turns
Φ = Flux
