Abstract
Currently, automobile consists of several electrical devices. These devices causes high supply current flowing through power and ground system in automobile. In this paper, we consider the effect of this current flow on ground system. The current flowing through ground system causes some ground voltage, which affects the performance of electrical devices. These ground voltages are generated by voltage drops between ground points and across the ground wires. When the supply current is larger, the voltage drop is higher. It is important to keep the ground voltage low for attaining the desired performance of the devices. Moreover, these ground voltages increase with time which further worsens the performance of electrical devices. This affects the durability of the electrical circuit of the automobile and hence the overall performance of automobile also deteriorates. Hence, we need to analyze this ground voltage increase, its causes and find out how to suppress this variation to maintain the automobile performance for long time. This is related to many factors, and our approach is from the ground voltage point of view.
