Nettetphotocurrent produces a voltage across a load resistor in parallel with the shunt resistance. Since, in the reverse biased mode Rdis substantially constant, large values of Rl may be used still giving a linear response between output voltage and applied radiation intensity. This form of circuit is required for high speed of response. Nettet21. apr. 2024 · As shown in Figure 2.3. 1, just the opposite behavior is observed in the photoelectric effect. The intensity affects the number of electrons, and the frequency affects the kinetic energy of the emitted electrons.

Thus, intensity affects how many photoelectrons are emitted (remember one photon can only dislodge one electron - 'all or nothing'). This photoemission can only happen if each photon carries sufficient energy to knock electrons out. And this is dependent on frequency, since E = h f.

Nettet27. okt. 2015 · 1. Online, I found a graph of photocurrent vs. stopping voltage: And I can’t figure out how photocurrent and stopping voltage have such a relationship. Stopping voltage is proportional to maximum KE and photon frequency, but neither of those factors really affect photocurrent as long as the threshold is reached. I would appreciate …

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.
