A cathode emits `1.8xx10^(17)` electron per second and all the electrons reach the anode when it Is given a positive potential of `400V`. Given `e=1.6xx10^(-19)`C, the maximum anode current is .

The cathode its 8 xx 10^(14) electrons per second, when heated. When 400 V is applied to anode all the emitted electrons reach the anode. The charge on electron is 1.6 xx 10^(-19)C . The maximum anode current is
