This study discusses the variations of photoelectric current with intensity of light. The photoelectric effect is dependent upon various factors including frequency of light, intensity of light, nature of material, energy of light and potential difference. However, even if the photoelectric effect is caused, the photoelectric current which is produced as a result of it may vary if intensity of light is changed, provided that frequency of illumination is greater than threshold frequency. To determine the impact of changing light intensity on photoelectric effect while keeping the other factors constant, an experiment was performed. The impact was seen by changing the distance of light source from photocell and the recording the readings on Microammeter. The correlation and graphical analysis was done to draw the results. The correlation analysis showed a significant positive relationship between photoelectric current and intensity of light. The graphical analysis also highlighted a positive linear relationship. Therefore, it was concluded that intensity of light directly affects the variations in photoelectric current.
