Name the type of transformer.

What is the principle of a transformer?

What is efficiency of a transformer?

There are 10000 turns in a trànsformer. Voltage in the primary is 0.2A. The transformer is wound so as to get a current 0.4A in the secondary. What type of transformer is this?

The input voltage of a transformer is 240 V AC . There are 80 turns in the secondary coil and 800 turns in the primary. What is the output voltage of the transformer ?

A transformer without power loss carries 4000 turns in the primary and 2000 turns in thw secondary. If the primary voltage is 120 V and the current is 0.2 A . What is the output voltage of transformer ?

Primary of a transformer has 20,000 turns and the secondary has 30,000 turns. 160V AC is applied at the primary ofthe transformer? lf the number of turns in the secondary transformer is greater than that in the primary then more voltage is induced in the secondary. Why?

Which type of transformer is there in a sub station ?
