Q. A 75-kVA transformer has an iron loss of 1 kW and a full-load copper loss of 1 kW. If the transformer operates on the following load cycle, determine the all-day efficiency:
8 hours full load at unity power factor
8 hours no load
8 hours one-half full load at unity power factor
A 15 volts source is applied to a series 150 mH inductor and 169 pF capacitor. The resistance of the inductor plus the connecting wires is 1,6 W. Determine the voltage drop and
