Which quantity is increased in a step down transformer?
- A Power
- B Current
- C Frequency
- D Voltage
Answer & Solution
Correct Answer
(B) Current
Step-by-step Solution
Detailed explanation
In a step-down transformer, the output voltage is decreased. To conserve energy (since Power = Voltage Current), the current must increase in the secondary coil to compensate for the drop in voltage. B) Current
