Question

A transformer has 600 turns on its primary and 200 turns on its secondary. (a) Is it a step-up or a step-down transformer? (b) If a voltage of $100 \mathrm{~V}$ is applied to the primary and a current of $0.25$ A flows in these windings, then what are the voltage output of the secondary and the current in the secondary?

Step 1

Given that the primary has 600 turns and the secondary has 200 turns, we can calculate the turns ratio: $$\text{Turns ratio} = \frac{\text{Number of turns in primary}}{\text{Number of turns in secondary}} = \frac{600}{200} = 3$$ Since the turns ratio is greater Show more…
