Faraday - Lenz law (for a tightly wound coil of wire)

Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. The induced ... more

Potentiometer Voltage Divider

Potentiometer is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider. The potentiometer can be used as a voltage ... more

Apparent power

The power factor of an AC electrical power system is defined as the ratio of the real power flowing to the load, to the apparent power in the circuit. In a ... more

Damping factor (Series RLC circuit)

Damping is caused by the resistance in the circuit. It determines whether or not the circuit will resonate naturally. Circuits which will resonate in this ... more

Plane wave ( in the positive x direction)

In the physics of wave propagation, a plane wave is a constant-frequency wave whose wavefronts (surfaces of constant phase) are infinite parallel planes of ... more

Electrical Mobility in gas phase

Electrical mobility is the ability of charged particles (such as electrons or protons) to move through a medium in response to an electric field that is ... more

Voltage (AC)

Alternating current voltage can be described mathematically as a function of time, angular frequency and peak voltage
