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

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

In a step up transformers, 220V is converted into 200V . The number of turns in primary coil is 600 . What is the number of turns in the secondary coil?

In the secondary coil of step-up transformer , the number of turns are ___

The input voltage and output voltage in the primary and secondary coils of a transformer are 250 V and 5 V, respectively. If the number of turns in the primary coil of the transformer is 1000, find the number of turns in its secondary coil. Also mention, whether the transformer is a step-up one or a step-down one ?

In a step - down transformer the input voltage is 22kV and the output voltage is 550V The ratio of the number of turns in the secondary to that in the primary is .

A step - up transformer is used on 120 V line to provide a potential difference of 2400 V . If the number of turns in the primary is 75, then the number of turns in the secondary shall be
