**maximum photocurrent ejected by electrons in photoelectric effect**
In a photoelectric effect experiment, unpolarized beam of light is incident on a metal surface. Power is given as 28.0mW; frequency of the beam is 7.4* 10^14Hz; and stopping potential Vs as 1.45V.
-I was able to find the wavelength of the beam of light as 405nm.(c/f)
-Energy in the photon as 3.06eV. (hf)
-Max speed of the electrons ejected as 7.1*10^5m/s. [sqrt(2K.E_max/mass)]
-Work function as 1.61eV. (E_photon - KE_max)
But I'm stuck now. I am also supposed to determine the maximum photocurrent that could be produced by the ejected electrons; but I don't have any formula that calculates the photocurrent and I could not derive any.
Could anyone help please?
Thanks.
