Question

To increase the current in a photocell significantly,

• A. energy of incident radiation is increased.
• B. frequency of incident radiation is increased.
• C. wavelength of incident radiation is increased.
• D. the cell is filled with a suitable inert gas eg. Helium, Neon etc.

Answer 1

The correct option is D the cell is filled with a suitable inert gas eg. Helium, Neon etc.

To increase the current in a photocell, intensity to be increased or simply fill the cell with suitable inert gas.

$\therefore$ Option $\left(D\right)$ is correct.

Why this Question? This question discussses alternate method of increasing current in photocell.
