Build an intuitive understanding of current and voltage, and power. Voltage and current are the cornerstone concepts in electricity. We will create our first mental models for these basic electrical quantities. We will also talk about power, which is what happens when voltage and current act together.
In electrical and electronic circuits, there are five major electrical quantities that used to analyze circuits. These quantities are electric charge, electric current, voltage, electric power and electrical energy. In this article, we shall learn about these quantities in detail.
Electrical & electronic units of electric current, voltage, power, resistance, capacitance, inductance, electric charge, electric field, magnetic flux, frequency.
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 Quantities: The Basic electrical quantities are charge, current, voltage, power, and energy. Their units are Coloumb, Ampere, Volt, watts, and Jules respectively.
How electrical charge relates to voltage, current, and resistance. What voltage, current, and resistance are. What Ohm's Law is and how to use it to understand electricity.
Formulas for Basic Electrical Quantities and Parameter. 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).
