The charge on one electron is 1.6 x 10-19 Coulombs. The electron beam in an oscilloscope has 3.4 x 107 electrons
flowing per second and the accelerating voltage is 15 kV.
What is the effective resistance of the space the electrons
flow through?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
