In a transformer, the ratio of the number of turns in the secondary coil to that in the primary coil is 10:3. Such a transformer is called_______transformer.

If the input voltage of a transformer is 2500 volts and output current is 80 ampere . The ratio of number of turns in the primary coil to that in secondary coil is 20 : 1 . If efficiency of transformer is 100 % , then the voltage in secondary coil as :

If the input voltage of a transformer is 2500 volts and output current is 80 ampere . The ratio of number of turns in the primary coil to that in secondary coil is 20 : 1 . If efficiency of transformer is 100 % , then the voltage in secondary coil as :

The number of turns in secondary coil of a transformer is 100 times the number of turns in primary coil. What is the transformer ratio ?

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 ?

In transformer , power of secondary coil is :

In transformer , power of secondary coil is :
