Other Quantities of electrical engineering
There are some other quantities in Electrical engineering, they are categorized below,
The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. The inverse quantity is electrical conductance, and is the ease with which an electric current passes. The symbol of resistance is R. the following equation is used to measure the resistance
Capacitance is the ability of a component or circuit to collect and store energy in the form of an electrical charge. The SI unit of capacitance is the farad (symbol: F), named after the English physicist Michael Faraday. A 1 farad capacitor, when charged with 1 coulomb of electrical charge, has a potential difference of 1 volt between its plates
The following equation is used to measure the capacitance (C) of a capacitor: C = Q/V, where Q is the amount of charge stored on each plate (Q) and V is the voltage of the battery.
In electromagnetism and electronics, inductance is the property of an electrical conductor by which a change in current through it induces an electromotive force in both the conductor itself and in any nearby conductors by mutual inductance
The symbol L for inductance was chosen to honor Heinrich Lenz (1804–1865), whose pioneering work in electromagnetic induction was instrumental in the development of the final theory
Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. In quantitative terms, it is the complex ratio of the voltage to the current in an alternating current (AC) circuit
Impedance, denoted Z, is an expression of the opposition that an electronic component, circuit, or system offers to alternating and/or direct electric current. Impedance is a vector (two-dimensional)quantity consisting of two independent scalar (one-dimensional) phenomena: resistance and reactance.
In electrical engineering, admittance is a measure of how easily a circuit or device will allow a current to flow. It is defined as the reciprocal of impedance. The SI unit of admittance is the (symbol S); the older, synonymous unit is mho, and its symbol is ℧ (an upside-down uppercase omega Ω).
