The grids in CRO are at:
Correct answer: C. Negative potential w.r.t to cathode
- A. Negative potential w.r.t to anode
- B. Positive potential w.r.t to anode
- C. Negative potential w.r.t to cathode
- D. Both (a) and (b)
Explanation
The grids in a CRO are typically at a negative potential with respect to the cathode. This negative potential helps control the flow of electrons emitted by the cathode towards the screen.

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.
