Q3. What is Ohm's law?
Ans. 
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's law is represented by the equation I = V/R, where I is the current, V is the voltage, and R is the resistance.

• It is named after Georg Simon Ohm, a German physicist who first formulated this law.

• This law is applicable to all types of circuits, including DC and AC circuits.

• It is use...read more

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
