Question
A current source sends a current $\text{I}-\text{i}_0\cos(\omega\text{t}).$ when connected across an unknown load, it gives a voltage output of $\text{v}=\text{v}_0\sin[\omega\text{t}+(\frac{\pi}{4})]$across that load. then the voltage across the current source may be brought in phase with the current through it by.

Answer

  1. Connecting an inductor in series with the load
