Options

A. intensity of incident light
B. potential difference applied between the two electrodes
C. the nature of emitter material
D. frequency of incident light

Explanation

To solve the question regarding the independence of photoelectric current in the photoelectric effect, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Photoelectric Effect**: The photoelectric effect refers to the phenomenon where electrons are emitted from a material (usually a metal) when it is exposed to light (or electromagnetic radiation) above a certain threshold frequency.

2. **Identify Key Factors**: The photoelectric current is influenced by several factors, including:
- **Intensity of Incident Light**: This affects the number of photons hitting the surface and thus the number of emitted electrons.
- **Frequency of Incident Light**: This affects the energy of the emitted electrons but not the number of electrons emitted if the frequency is above the threshold.
- **Material Properties**: The work function of the material determines the threshold frequency.
- **Voltage Applied**: The applied voltage can affect the collection of emitted electrons, thus affecting the current.

3. **Determine Independence**: The question asks for the factor that the photoelectric current is independent of.
- The photoelectric current is directly proportional to the intensity of the incident radiation (more photons lead to more emitted electrons).
- The photoelectric current is also affected by the applied voltage.
- The frequency of the incident light, however, only affects the kinetic energy of the emitted electrons and does not affect the number of electrons emitted (as long as the frequency is above the threshold). Therefore, the photoelectric current does not depend on the frequency of the incident light.

4. **Conclusion**: Based on the analysis, we can conclude that the photoelectric current is independent of the frequency of the incident light.

### Final Answer:
The photoelectric current is independent of the frequency of the incident light.
