- 4regulate the fluctuation of voltage
Select the correct answer using the code given below.
general-sciencephysics
- A1 and 3
- B3 and 4
- C1 and 2
- D1, 2 and 3
Explanation
A transformer steps AC voltage up or down; it does not convert DC to AC (an inverter does) nor merely regulate fluctuation - only statements 1 and 2 are correct.
