Module 3. Electrical fundamentals

Which of the following would be used to calculate transformer turns ratio?

  • Secondary turns / primary turns.
  • Primary turns * secondary turns.
  • Primary turns / secondary turns.

Explanation

The transformation ratio used to find the output is secondary turns divided by primary turns, since Vs = Vp x (Ns/Np). Multiplying the turns together has no physical meaning, and primary divided by secondary would give the inverse ratio, predicting the opposite of the actual voltage change.

sasna asking:

transformer ratio and turn ratio are reciprocal...???
