By means of waveform displayed on the screen of CRO, we can measure:
Correct answer: D. All of above
- A. Frequency of voltage
- B. Voltage
- C. Phase of voltage
- D. All of above
Explanation
A CRO is indeed capable of measuring frequency and displaying voltage waveforms, so this option is not accurate.

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.
