Given V1 = 220 V, V2 = 440 V, I1 = 10 A, and I2 = 5 A, verify the transformer equation V2 / V1 = I1 / I2.

1. True
2. False
3. Cannot be determined
4. None of the above

Correct answer: True

Solution

The transformer equation states that V2/V1 = I1/I2. Substituting the given values: V2/V1 = 440/220 = 2 and I1/I2 = 10/5 = 2. Since both sides are equal, the equation is verified as true.
