Answer: A (,309.8°)
B (2, 315°)
C (, 26.56°)
Explanation: To transform rectangular coordinates into polar coordinates use:
and
For point A:
°
Point A is in the II quadrant, so we substract the angle for 360° since it is in degrees:
309.8°
Polar coordinates for point A is (, 309.8°)
For point B:
°
Point B is in IV quadrant, so:
315°
Polar coordinates for point B is (, 315°)
For point C:
26.56°
Polar coordinates for point C is (, 26.56°)

Answer:
Part 1) Voltage in secondary windings is 61.08 Volts
Part 2) Current in secondary windings is 0.53 Amperes
Explanation:
The potential developed in the primary and secondary winding of a transformer are related as
where
Np no of turns in primary coil
Ns no of turns in secondary coil
Vp Voltage of turns in primary coil
Vs Voltage of turns in secondary coil
Applying values in the formula we get
Part 2)
Using Ohm's law the current is given by
