Answer to Question #255860 in Electrical Engineering for A jaif

Question #255860

A 50 Hz, 885 V/88.5 V transformer is used for stepping down voltage. Its HV winding resistance and reactance are 90 ohms and 85 ohms respectively and its LV winding resistance and reactance are 9 ohms and 8.5 ohms respectively. Its core-loss as measured from the primary side = 6 W. The load connected to it = 6 + j7 ohms.

What is the value of its core-loss resistance in k.ohms when looked from the primary side?


What is its core-loss in W when looked from the secondary side?


What is the magnitude of the current that flows through the given load in A?


What is the power consumed in the load in W?


What is the magnitude of the current that will be flowing into the primary winding in A if the excitation current is neglected?
