If the windings of a certain transformer with a turn ratio of 1 are in opposite directions around the core, tbe secondary voltage is ____ the primary voltage. AND WHY???? A. in phase with B. out of phase with C. greater than D. less than
Added by Allen G.
Step 1
In this case, the turn ratio is 1, which means the number of turns in the primary and secondary windings are equal. Secondly, the direction of the windings affects the phase of the output voltage. If the windings are in the same direction, the primary and Show more…

For a conceptual single-phase phase-shifting transformer, the primary voltage leads the secondary voltage by 308. A load connected to the secondary winding absorbs 110 kVA at an 0.8 power factor leading and at a voltage E2 = 277 (angle of 0 degrees) volts. Determine (a) the primary voltage, (b) primary and secondary currents, (c) load impedance referred to the primary winding, and (d) complex power supplied to the primary winding.
