No, the electric field applied to the metal plate will only take effect once the electron is ejected from the surface (once it has gotten over the work function of the surface) once it is a free electron and assuming it is in a vacuum only then will the electron be accelerated. In fact this is the principal by which a PM (Photo Multiplier) tube works. The ...

If the plate has negative charge, then yes. Freed electrons will be accelerated away from the plate by the electric field, gaining energy above what they acquired from absorbing a photon. If the plate is positively charged, then the opposite occurs- moving against an attractive electric field robs the emitted electrons of energy, and the positive charge ...

The term Resistance does not come into play while dealing with Photoelectric Effect. The latter is related to the emission of electrons when the surface of a metal(or any substance) is hit by photon particles(photon is the unit particle making up the light that we talk of). Here the more important concept is that of Work Function, i.e. the minimum amount of ...

does this mean that Ohm's law just fails in this case Ohm's law is not universal. The ideal resistor circuit element is defined by Ohm's law but not all circuit elements obey Ohm's law; Ohm's law only applies to ohmic devices. Physical resistors and conductors approximately obey Ohm's law but, for example, semiconductor diodes, transistors, ...

Suppose you have an object which is a perfect absorber/emitter of electromagnetic radiation, a.k.a. a "black body". Suppose we try to compute the electromagnetic power radiated by this object using statistical mechanics and classical electromagnetic theory. We would find that the object emits electromagnetic radiation at all wave lengths, and the wave length ...
