Relations between polarization density and electric displacement field

In classical electromagnetism, polarization density (or electric polarization, or simply polarization) is the vector field that expresses the density of ... more

Reluctance

Magnetic reluctance, or magnetic resistance, is analogous to resistance in an electrical circuit (although it does not dissipate magnetic energy). In ... more

Resistances connected in series

In a series configuration, the current through all of the resistors is the same, but the voltage across each resistor will be in proportion to its ... more

Resistances connected parallel

If two or more components are connected in parallel they have the same potential difference (voltage) across their ends. The potential differences across ... more

Resistor Actual Power (for Voltage difference)

Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule ... more

Resistors in parallel

Resistors in a parallel configuration are each subject to the same potential difference (voltage), however the currents through them add

Resonance frequency in LC circuits

An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter ... more

Resonance frequency in LC circuits (angular)

An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter ... more

Resonance frequency RLC

Resonance frequency is the ability of a circuit to resonate at a specific frequency, the resonance frequency related to the angular frequency

Richardson's law

Thermionic emission is the thermally induced flow of charge carriers from a surface or over a potential-energy barrier. This occurs because the thermal ... more
