Q1. What is Ohm's Law?
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• For example, if a circuit has ...read more

Q1. What is type of VCB coil....
Ans. 
The type of VCB coil is generally a copper coil.
• VCB coils are typically made of copper due to its high conductivity and durability

• Copper coils are preferred for VCBs as they provide efficient current flow and are resistant to heat

• Some VCB coils may also be made of aluminum, but copper is more common

Q2. Which types of transformer losses
Ans. 
Transformer losses include copper losses and iron losses.
• Copper losses are caused by the resistance of the copper windings and increase with the square of the current flowing through the transformer.

• Iron losses, also known as core losses, are caused by hysteresis and eddy currents in the transformer core material.

• Other losses may include stray losses, dielectric losses, and mechanical losses.

• Total losses in a transform
