In CRO, there are:
Correct answer: B. Two sets of deflecting plates
- A. Power deflecting plates
- B. Two sets of deflecting plates
- C. Three sets of deflecting plates
- D. None of these
Explanation
In a CRO, there are typically two sets of deflecting plates, one for horizontal deflection and the other for vertical deflection. By controlling the voltages applied to these plates, the electron beam can be moved horizontally and vertically across the screen to display the waveform.

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.
