Question

What type of deflection mechanism used in cro to deflect electron beam?

Answer 1

By impressing voltages between these plates the motion of the electron beam and the trace on the fluorescent screen can be controlled. Sometimes external magnetic deflecting coils are used. The fluorescent screen consists of a suitable m

Answer 2

Most smaller CRTs use electrostatic deflection, which occurs when the electron beam is deflected as it passes through charged metal plates; the direction of deflection depends on the amount of charge and polarity of the plates.
