The average power delivered during a cycle is:
Correct answer: B. I2R
- A. Zero
- B. I2R
- C. One
- D. V2I
Explanation
The explanation is: The average value of alternating voltage or alternating current over a cycle is zero, but the power delivered in one complete cycle is not zero (P = I2R or P = V2/R). Power P = Voltage V x Current I but V=IR so, P=I x IR P = I2R

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.
