For a synchronous generator the synchronous impedance Xs is j3.8. This generator is delivering 3900 A at unity power factor to a load, at its terminal at a voltage of 13.8 kV (line-to-line). What is absolute value of the line-to-neutral internal Voltage, E0?

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
