QUESTION 27 For a transformer, if the primary voltage and current are 1A and 100V, hich combination of secondary voltage and current below is possible? O a. 1A, 50V O b. 2A, 100V C. 2A, 50V O d. 1A, 200V

Solution

A transformer maintains constant KVA on both sides, as it is a constant power device.

Input KVA=1*100=100KVA

Option C also provides 100KVA.

So C is answer.
