What is the turns ratio for a transformer with 50,000 primary turns and 1,000 secondary turns?

To determine the turns ratio of a transformer, you can divide the number of primary turns by the number of secondary turns. In this case, with 50,000 primary turns and 1,000 secondary turns, the calculation is as follows:

Turns ratio = Number of primary turns / Number of secondary turns

Turns ratio = 50,000 / 1,000 = 50

This results in a turns ratio of 50:1, indicating that for every 50 turns on the primary side, there is 1 turn on the secondary side. This ratio helps in understanding how voltage transforms between the two sides of the transformer.

So, the correct representation of this turns ratio is 50:1. The option representing this relationship reflects the fundamental principles of transformer operation, where a higher turns ratio indicates a step-down transformer in this context.
