An industrial plant consumes 500 kWat a lagging power factor of 0.6.
(a) Find the required kVA rating of a synchronous capacitor to improve the power factor to 0.9.
(b) If a 500-hp, 90% ef?cient synchronous motor, operating at full load and 0.8 leading power factor, is added instead of the capacitor in part (a), calculate the resulting power factor.
For a given logic family, consider VOL = 0.25V and VOH = 5 V . For a given circuit, VIL = 0.96 V and VIH = 2.18 V. Find the largest positive-going and largest negative-going nois
