The direction of an electric field is determined by the movement of positive charges, pointing from high voltage to low voltage. While voltage magnitude indicates the strength of the electric field, it does not influence its direction. The common terminology in electronics designates positive voltage as 'high' and negative voltage as 'low,' which can lead to confusion. Ultimately, the electric field direction remains consistent regardless of the voltage's magnitude. Understanding this distinction clarifies misconceptions about voltage and electric field orientation.
