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 a step down transformer the number of turns in primary coil is greater than that of the number of turns in the secondary coil

A transformer working on a 240 V AC supplies 12V. The number of turns in the primary coil is 1000. Calculate 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?

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?

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

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
