The maximum velocity acquired by the electrons

Posted on 2014-01-23 12:35:00 in Engineering by CURTIS

The potential difference across the vacuum diode plates is 200V and the current through the diode is 20 mA. Determine (i) the maximum velocity acquired by the electrons, assuming their initial velocity zero (ii) the number of electrons passing per second from cathode to anode and (iii) the energy absorbed per minute in electron volts. It is given that electron charge = 1.6 x 10^-19 C and electron mass = 9.11 x 10^-31 kg.
