Q2. If a fan of 500watt is connected to a single phases line what ampare carent it is consumed
Ans. 
The fan consumes 4.17 Amps of current when connected to a single phase line.
• The formula to calculate current is I = P / V, where P is power in watts and V is voltage in volts.

• In this case, the fan consumes 500 watts of power and is connected to a single phase line with voltage typically around 120V.

• Therefore, the current consumed by the fan is 500W / 120V = 4.17A.

Q1. What is transformer,how its work.
Ans. 
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
• Transformers work on the principle of electromagnetic induction

• They have two coils, primary and secondary, wound around a magnetic core

• When an alternating current flows through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil

• Transformers are used...read more
