Photocurrent and Light Intensity
Photocurrent is the electric current that flows through a photosensitive material when it is exposed to light. The magnitude of photocurrent depends on various factors, including the intensity of light.
Explanation
The correct statement is option 'C': The photocurrent increases with increasing intensity of light. When a photosensitive material is exposed to light, electrons are excited from the valence band to the conduction band, creating electron-hole pairs. The electron-hole pairs then contribute to the photocurrent.
The intensity of light determines the number of electron-hole pairs created. The greater the intensity of light, the more electron-hole pairs are created, resulting in a higher photocurrent. This is because the energy of each photon of light is proportional to its frequency, and higher intensity means more photons are hitting the photosensitive material, and hence, more electrons are excited.
Therefore, increasing the intensity of light increases the number of electron-hole pairs created, resulting in a higher photocurrent.
