What is the formula of photoelectric current with explanation of every term

einsteins relation
hv – hv0 = ½ mv2
hv – energy of incident beam
hv0- work function (minimum energy required to observe photoelectric effect)
1/2mv2- kinetic energy with which the electron gets projected out if the energy of incident beam is greater than work function)
Thanks,
BEST OF LUCK

einsain gave the concept of photoelectric current , and acc to him the law is like the below
1- suppose some energy are supplied to the metal in the form of photon , then that energy will be utilised in two ways ,
(i) to eject the electron out of the metal , that is the work function .
(ii) the rest of the energy are used to give kinetic energy to the photoelectrons .
so, the equation will be formed like this
hv= phi + ½ mv square (max )
in whichg the term meanings are
hv = energy carries on the photon
phi- work function
1/2 mvsquare (max ) = max kinetic energy
there are many form of this equation , u can alaos equate k.e (max ) = ev0
