Q1. Different between kw vs kva?
Ans. 
kW measures real power while kVA measures apparent power in an electrical system.
• kW stands for kilowatts and represents the actual power consumed by a device or system.

• kVA stands for kilovolt-amperes and represents the total power in an electrical system, including both real and reactive power.

• The power factor (PF) is the ratio of real power (kW) to apparent power (kVA) in a system.

• kW is used to determine the actual en...read more

Q2. Definition of transformers?
Ans. 
Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.
• Transformers consist of two coils of wire, known as the primary and secondary coils.

• They work on the principle of electromagnetic induction, where a changing current in the primary coil induces a voltage in the secondary coil.

• Transformers are used to step up or step down voltage levels in e...read more
