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

Q3. How many types of Electricity ? Electricity 2 types 1:statics&2:Dynamic..
Ans. 
There are two types of electricity: static electricity and dynamic electricity.
• Static electricity is the buildup of electric charge on an object without any flow of electric current.

• Dynamic electricity is the flow of electric charge through a conductor.

• Examples of static electricity include rubbing a balloon on hair and getting shocked by touching a doorknob.

• Examples of dynamic electricity include the electricity flowi...read more

Q4. How much volt in Ht line ? Ans:11kv ,25kv,33kv,66kv,132kv,220kv,400kv,500kv
Ans. 
The voltage in HT lines can vary depending on the application, but common voltages include 11kV, 25kV, 33kV, 66kV, 132kV, 220kV, 400kV, and 500kV.
• HT lines typically carry higher voltages than low-tension lines.

• The voltage in HT lines is used for transmitting electricity over long distances.

• Higher voltage levels in HT lines reduce power losses during transmission.

• Examples of HT lines include transmission lines for power
