Read the following text and answer the following questions on the basis of the same:
Photocell: A photocell is a technological application of the photoelectric effect. It is a device whose electrical properties are affected by light. It is also sometimes called an electric eye. A photocell consists of a semi-cylindrical photo-sensitive metal plate C (emitter) and a wire loop A (collector) supported in an evacuated glass or quartz bulb. It is connected to the external circuit having a high-tension battery B and micro ammeter (µA) as shown in the Figure.
Sometimes, instead of the plate C, a thin layer of photosensitive material is pasted on the inside of the bulb. A part of the bulb is left clean for the light to enter it. When light of suitable wavelength falls on the emitter C, photoelectrons are emitted. These photoelectrons are drawn to the collector A. Photocurrent of the order of a few microampere can be normally obtained from a photo cell. A photocell converts a change in intensity of illumination into a change in photocurrent. This current can be used to operate control systems and in light measuring devices.
Q. Photosensitive material should be connected to
  • a)
    –ve terminal of the battery.
  • b)
    +ve terminal of the battery.
  • c)
    any one of (A) or (B).
  • d)
    connected to ground.
Correct answer is option 'A'. Can you explain this answer?
