Question 1
A transformer has 150 turns on the primary winding and 30 turns on the secondary winding. If the primary voltage is 120V, calculate the secondary voltage and current if the primary current is 2A.
💡 Hint: Apply the voltage and current ratio formulas.
Question 2
Explain what would happen if a transformer designed to step down voltage from 400V to 40V is connected in reverse. Discuss the implications for current and power.
💡 Hint: Consider energy conservation and the results of mismatch.
