Photoelectric effect experiment

[chialer96]

What are the possible systematic/random error that can affect my experimental results?

Unless you give us more details on the goal of the experiment and the nature of the apparatus, the only answer you can get is "lots".

Photoelectric effect experiment. Light with different frequencies are shone onto a photodiode therefore a current is produced. We apply a stopping voltage to the current to cease the kinetic energy of electrons. Stopping voltage is plotted against frequency of photons. The graph will cut at a y intercept which we knownas work function. Now we compared our experimental value of Planck's constant to the actual one. Obviously we will get a percentage error. Now I need help with the possible errors
