Question 1

A transformer has a turns ratio of 10:1. If the primary voltage is 500V and the primary current is 2A, determine the secondary voltage and current.

💡 Hint: Use the turns ratio to find voltage and then apply the current formula.

Question 2

Consider a transformer that steps down voltage from 480V to 120V supplying a load of 10A on the secondary side. What is the primary current?

💡 Hint: Remember the inverse relationship between current and voltage.
