A load consisting of induction motors is drawing 40 kW average real power from a 110-V (RMS), 6 Hz power line at a power factor of 0.7. We need to improve the p.f. to 0.9. a) Are we going to add a capacitor or an inductor to correct the power factor? b) How large is the capacitor or inductor? Add a capacitor in series with load and C= 247UF Add a capacitor in parallel with the load and C= 4699uF O Add an inductor in series with load and L- 30uH O Add an inductor in series with the load andL= 0.9H
