An ideal transformer increases the input current 4A to 24A at the secondary. If the number of turns in the primary coil is 330 the number of turns in the secondary coil is

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 ?

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

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

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?

A transformer whose efficiency is 90%, draws 5 A when 200 V is applied to its primary coil. If output is drawn at 300 V, what is the current in secondary coil ? If number of turns in primary coil is 500, what is the number of turns in secondary coil?

In step-up transfomer, the relation between number of turns in primary (N_(p)) and number of turns in secondary (N_(S)) coils is

In a transformer, number of turns in the primary coil are 140 and that in the secondry coil are 280. If current i primary coil is 4A, then that in the secondary coil is
