Engine: Electricity

1. A The transformer functions as a filter by removing the DC component from the varying DC input to produce an AC output shifted 90 from the input.
2. B The transformer functions as a filter by removing the DC component from the varying DC input to produce an AC output in phase with the input.
3. C The transformer functions as a voltage transformer by changing the magnitude of the peak to peak AC voltage at the output proportional to the turns ratio.
4. D The transformer functions as a filter by removing the DC component from the varying DC input to produce an AC output shifted 180 from the input.
