Q2. Transformer functioning and principal
Ans. 
Transformers are electrical devices that transfer energy between two or more circuits through electromagnetic induction.
• Transformers work on the principle of electromagnetic induction

• They consist of primary and secondary coils wrapped around a core

• Step-up transformers increase voltage while step-down transformers decrease voltage

• Efficiency of transformers is determined by the ratio of output power to input power

Q4. Working of induction motor
Ans. 
An induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.
• Consists of a stator and a rotor

• Stator has a set of coils that produce a rotating magnetic field

• Rotor is made up of conductive bars and is placed inside the stator

• The rotating magnetic field induces a current in the rotor, which in turn produces a magnetic field

• The interaction between the two magne...read more
