In an ideal transformer, number of turns in primary and secondary are 200 and 1000 respectively. If the power input to the primary is 10 kW at 200 V, calculate current in parimary.

In an ideal transformer, the number of turns in primary and secondawry coils are 2,000 and 100 respectively. If maximum votlage in primary is 120 V, what is maximum voltage in secondary?

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if assertion is true, but reason if false, (D) if both assertion and reason are false Assertion : In a transformer, the number of turns in the primary and secondary coils are 500 and 1,250 respectively. If the current in primary coil is 2 A, then the current in secondary coil will be 5 A. Reason : The current in secondary coil is given by I _ s = Ip xx (N_s)/(N_P)

Ratio of number of turns in primary and secondary coil of 440V-22000V step up transformer is

The number of turns in the primary and secondary coils of a transformer are 1000 and 3000 respectively. If a 80 V, a.c. supply is applied to the primary coil of the transformer, then the P.D. Per turn of the secondary will be

In a transformer, number of truns in the primary is 140 and that in th secondary is 280. If current is primary is 4 A, then that in the secondary is

Efficiency of a transformer is 80% and primary and secondary coils hae 30 and 120 turns respectively. Current in the secondary coil is 0.25 A. Find out the current in primary coil.

Calculate the current drawn by the primary windlings of a step-down transformer, whose primary and secondary voltages are 220V and 22V rspectively. A load resistance of 22 ohm is connected to its secondary windings and it operates at an efficiency of 75%.
