Question

In a photoelectric effect experiment, the photo current becomes zero when a

potential -3 V is applied to anode. If work function of the cathode is 2 eV, calculate

the energy of photon incident on the cathode.​

Answer 1

current may increase as now the electrons in the wire will be under greater potential difference thereby reducing the time in which the electrons complete one round to reach the same point again and hence increasing current. (V=IR)

current may not be continuous (steady current might not be achieved) as the time taken by the photoelectrons to reach the positive electrode may be more than the time taken by the electrons inside the wire to go from end of the wire nearer to the positive electrode to the other end.
