In a primary coil `5A` current is flowing on `220` volts. In the secondary coil `2200V` voltage produces. Then ratio of number of turns in secondary coil and primary coil will be

A current of 5A is flowing at 220V in the primary coil of a transformer. If the voltage produced in the secondary coil is 2200V and 50% of power is lost, then the current in the secondary coil will be –

A transformer steps an A.C voltage from 230 V ot 2300 V . If the number of turns in the secondary coil is 1000, the number of turns in the primary coil will be

In a transformer 220 ac voltage is increased to 2200 volts. If the number of turns in the secondary are 2000, then the number of turns in the primary will be

In an ideal transformer, the voltagae and the current in the primary coil are 200V and 2 A, respectively. If the voltage in the secondary coil is 200 V, then the value of current in the secondary coil will be

A transformer steps up an A.C. voltage from 230 V to 2300 V. If the number of tunrs in the secondary coil is 1000, the number of turns in the primary coil will be

The primary coil of an ideal transformer has 100 turns and the secondary coil has 600 turns. Then

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 :

A step down transformer is used at 220 V to provide a current of 0.5 A to a 15 W bulb. If the secondary has 20 turns, find the number of turns in primary coil has current that flows in primary coil.
