Intensity vs photocurrent graph

Nettet29. mar. 2024 · It is so because as you increase the voltage the number of electrons reaching the other plate increases because more of them have the required energy to do so until a point is reached where all the electrons released from the plate on which light is shone constitute the photo current. Nettet13. apr. 2024 · In the I–V graph, slight non-linearity has been found under dark condition and also found to increase with the increase in incident light intensity. According to Fig. 5 , the photocurrent was found to increase with the incident light intensity and obtained the maximum under 5.436 mW/cm 2 red laser light.

Photocurrent VS stopping voltage and intensity of light

NettetAt the points where curve cuts the x axis, the incident photon energy is equal to the work potential of material. Hence energy, hence frequency, is same for radiation of curves a & b. Intensity is the measure of number of photons striking per unit time. Thus they determine the amount of photocurrent produced. Thus it is same for b & c.

NettetCurrent is flow of electrons in a given time i.e if the intensity of the light is Constant then Photons incident on Cathode (ejector plate) is also constant. As we know that minimum K.E, that photo-electron can have is 0 and max. is energy of the photons minus the work function of the material. Nettet22. sep. 2024 · In my opinion this graph isn't the graph for the conditions as mentioned rather, it should be for light with same number of photons incident per unit time per unit …

Nettet20. jan. 2012 · A change in photon frequency is a change in energy, not a change in the rate at which photons appear (that's intensity). Thus the number of photons is the intensity, which determines the number of electrons produced, which is the current.. The photon frequency, AKA photon energy, determines the kinetic energy of the electrons … NettetFrom the graph in Figure 7.9, it is evident that photocurrent – the number of electrons emitted per second – is directly proportional to the intensity of the incident light. …
