You can learn about electric current by following the attached link. Meanwhile, students can also check the important formulas for this topic below. Electric current is measured in amperes (A), which represents the amount of charge passing through a point in a conductor per second. There are two main types of electric current: Direct Current (DC): The flow of electric charge is in one constant direction. Alternating Current (AC): The flow of electric charge periodically reverses direction. Alternating Current Formula The formulas for alternating current (AC) primarily describe how voltage and current fluctuate over time. AC analysis focuses on key aspects such as instantaneous values, the relationship between peak and RMS (Root Mean Square) values, and the calculation of power. Basic Voltage, Current, Power and Resistance Formulas in AC and DC Circuits Following are the electrical engineering formulas and equations for the basic quantities i.e. current, voltage, power, resistance and impedance in both DC and AC circuits (single phase and three phase).
