Q2. What is annealing
Ans. 
Annealing is a heat treatment process used to reduce hardness and increase ductility of a material.
• Annealing involves heating a material to a specific temperature and then slowly cooling it down.

• This process helps to relieve internal stresses, improve machinability, and enhance electrical conductivity.

• Common examples include steel annealing to improve its ductility and copper annealing to increase its conductivity.

Q1. Explain power fector
Ans. 
Power factor is a measure of how effectively electrical power is being used in a circuit.
• Power factor is the ratio of real power to apparent power in an electrical circuit.

• It is a number between 0 and 1, with 1 representing perfect efficiency.

• A low power factor indicates that a circuit is not using electrical power efficiently.

• Power factor can be improved by adding power factor correction capacitors to the circuit.

Q2. Explain transformer primary winding and secondry winding
Ans. 
Primary winding receives electrical energy from the source while secondary winding delivers the transformed energy to the load.
• Primary winding is connected to the input voltage source

• Secondary winding is connected to the load

• Primary winding has fewer turns than secondary winding to step up voltage

• Secondary winding has more turns than primary winding to step down voltage
