Light intensity is the result from the Kerr effect measurement that can be used in determining the electric field distributions in dielectric liquids as the analysis continues afterwards. One of the most important parameters to consider in designing the Kerr effect experiment is the Kerr constant of the test liquid. This paper aims to study and compare light intensity distribution in different dielectric liquids using Kerr effect method. Propylene carbonate, transformer oil and purified water are used as the test liquids. From the results obtained, the light intensities as a function of electric field of the test liquids are compared. With higher Kerr constant, low voltages can be applied to the test liquid but with larger optical signals. Furthermore, the length of the electrodes can be designed accordingly to suit the experimental setup.
