Find the elements of the equivalent circuit relative to the secondary of a single-phase transformer. The no- load voltages in the primary and secondary circuit are 200 and 400 volts, respectively, and at a frequency of 50 Hz. The primary no-load current at a voltage of 200 volts is 0.7 amps and the losses in the core are 70 watts. The resistance and reactance of the primary are 3.2 and 1.25 ohms, respectively. Secondary resistance and reactance 6. 0. 0.07 ohms.

Question
Find the elements of the equivalent circuit relative to
the secondary of a single-phase transformer. The no-
load voltages in the primary and secondary circuit are
200 and 400 volts, respectively, and at a frequency of
50 Hz. The primary no-load current at a voltage of
200 volts is 0.7 amps and the losses in the core are 70
watts. The resistance and reactance of the primary
are 3.2 and 1.25 ohms, respectively. Secondary
resistance and reactance 6. 0, 0.07 ohms,
respectively. Draw the equivalent circle, showing the
values of its elements.
