Photoelectric current depends on

(A) the intensity of incident light
(B) the potential difference applied between the two electrodes
(C) the nature of the emitter material
(D) the conductivity of the emitter material

Choose the correct answer from the options given below:

(A), (B) and (C) only

The correct answer is Option (2) → (A), (B) and (C) only

Photoelectric current depends on:

(A) The intensity of incident light — higher intensity increases the number of incident photons, thus more electrons are emitted, increasing the current.

(B) The potential difference applied between the two electrodes — affects the collection of emitted electrons; a higher positive potential increases the current until saturation.

(C) The nature of the emitter material — affects the work function; different materials emit electrons differently under the same light.

(D) The conductivity of the emitter material — does not directly affect the photoelectric current.

Correct dependencies: (A), (B), (C)
