An ideal transformer is used to decrease an alternating voltage from 880 V and 220 V. If the number of turns of its primary coil is 4000, then what is that in the secondary coil?

A transformer decreases the alternating supply voltage from 2200 V to 220 V. If the number of turns in the primary coil of the transformer is 2000, calculate the number of turns in secondary.

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 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 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

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 is used to step up an alternating emf of 200V to 440V. If the primary coil has 1000 turns, calculate 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.
