If turns in primary = 50, secondary = 200, primary voltage = 120V, primary current 3A, then output power will be about:
Correct answer: A. 360W
- A. 360W
- B. 300W
- C. 460W
- D. Zero
Explanation
For ideal transformer Po=P1 Ip=3A Vp=120V P=(Ip)(Vp)=120 X 3 = 360W

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
