In a certain vacuum tube, electrons evaporate from a hot cathode at a slow, steady rate and accelerate from rest through a potential difference of 45.0 V. Then they travel 28.0 cm as they pass through an array of slits and fall on a screen to produce an interference pattern. If the beam current is below a certain value, only one electron at a time will be in flight in the tube. In this situation, the interference pattern still appears, showing that each individual electron can interfere with itself. What is the maximum value for the beam current that will result in only one electron at a time in flight in the tube?
The current of a beam of electrons, each with a speed of 900 m/s, is 5.00 mA. At one point along its path, the beam encounters a potential step of height -1.25 mV.What is the current on the other side of the step boundary?
The current of a beam of electrons, each with a speed of 1.200*10^3 m/s, is 9.000 mA. At one point along its path, the beam encounters a potential barrier of height -4.719 mV and thickness 200.0 nm.What is the transmitted current?
