Question

Suppose that the collector is held at a small negative voltage with respect to the grid. Will the accelerated electrons reach the collecting plate?
A)Yes, but only those electrons with energy less than the potential difference established between the grid and the collector will reach the collector.
B)Yes, but only those electrons with energy greater than the potential difference established between the grid and the collector will reach the collector.
C)Yes; all the accelerated electrons will reach the collector.
D)No, none of the electrons will reach the collector

Explanation / Answer

B) Yes, but only those electrons with energy greater than the potential difference established between the grid and the collector will reach the collector. if kinetic energy of accelerated electrons is greater than the potential energy caused due to negative potential, they can reach the collector.
