In a photocell, increasing the intensity of incident light increases `"……………….."`

Options

A. the stopping potential
B. the photoelectric current
C. the energy of the incidient photons
D. maximum kinetic energy of the photo-electron

Explanation

To solve the question regarding the effect of increasing the intensity of incident light in a photocell, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Photocell Basics**: A photocell operates on the principle of the photoelectric effect, where light incident on a material can eject electrons from that material.

2. **Defining Intensity**: Intensity of light is defined as the power per unit area. In the context of the photoelectric effect, increasing the intensity means increasing the number of photons hitting the surface per unit time.

3. **Effect of Intensity on Photoelectric Current**: When the intensity of light increases, more photons are incident on the photocell. If the frequency of the light is above the threshold frequency, this results in more photoelectrons being emitted.

4. **Photoelectric Current**: The photoelectric current is directly proportional to the number of photoelectrons emitted. Therefore, as the intensity increases, the number of emitted photoelectrons increases, leading to an increase in the photoelectric current.

5. **Analyzing Other Options**:
- **Stopping Potential**: The stopping potential is related to the maximum kinetic energy of the emitted electrons, which depends on the frequency of the incident light, not the intensity.
- **Energy of Incident Photons**: The energy of each photon is given by \(E = h \nu\), where \(h\) is Planck's constant and \(\nu\) is the frequency. Increasing intensity does not change the energy of individual photons.
- **Maximum Kinetic Energy of Photoelectrons**: This is determined by the frequency of the incident light, not the intensity.

6. **Conclusion**: Thus, the correct answer to the question is that increasing the intensity of incident light increases the **photoelectric current**.

### Final Answer:
In a photocell, increasing the intensity of incident light increases **the photoelectric current**.
