The paper studies electrical property of the optical current sensor based on Faraday magneto-optical effect. The optic axis angle between polarizer and polarizer analyzer mirrors, Faraday rotation angle' s impacts on the response waveform caused by alternating current, and the amplitude and frequency characteristics of response are simulated and studied according to Malus Law. The electrical property of this kind of optical current sensor is studied, which can provide solutions for experiments, and basis is provided for determining the parameters of the magneto-optical media. The simulation and part of experiment results show that this kind of optical current sensor has a good response waveform and amplitude, frequency characteristics in proper parameters.
