Basic Electrical Formulas Electrical Technology 12 volts ÷ 3 ohms = 4 amps. it’s as simple as that. let’s tackle another example to find a circuit’s resistance using the given values: voltage = 120v. current = 17 amps. now plug the known values into our formula wheel and work the equation. 120 volts ÷ 17 amps = 7.05 ohms. i told you it was simple. 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).
Basic Electrical Formula Chart The following chart provides a list of basic electrical formulas with definitions to calculate and measure basic electrical parameters and quantities. (formula chart is given below). voltage. voltage is the electric potential difference or electrical force that pushes electric charges through a circuit. its si measuring unit is the “volt. Generally, electrical power is dissipated in the form of heat (heaters), mechanical work such as motors, energy in the form of radiated (lamps) or as stored energy (batteries). electrical energy in circuits. electrical energy is the capacity to do work, and the unit of work or energy is the joule ( j ). electrical energy is the product of power. The three basic principles for this tutorial can be explained using electrons, or more specifically, the charge they create: voltage is the difference in charge between two points. current is the rate at which charge is flowing. resistance is a material's tendency to resist the flow of charge (current).
