Q1. How to charge the Transformer?
Ans. 
A transformer can be charged by applying a voltage to its primary winding.
• To charge a transformer, connect a power source to its primary winding

• The voltage applied to the primary winding creates a magnetic field

• This magnetic field induces a voltage in the secondary winding

• The transformer is charged and ready to transfer power
