Q1: In a Vidicon camera tubeA
grid G1 accelerates electrons
B
grid G2 accelerates electrons and grid G3, slows down electrons
C
grid G3 accelerates electrons and grid G2 slows down electrons
D
both grids G2 and G3 accelerate electrons
ANS:B - grid G2 accelerates electrons and grid G3, slows down electrons Grid G2 accelerates the electrons. Grid G3, is focus grid and slows the electrons so that they fall perpendicularly on the target at a low speed without causing secondary emission. |
