In electronics, a vacuum tube, an electron tube, or colloquially a tube (North America) or valve (British usage), is a device that controls electric ... more

Electric power is the rate at which electric energy is transferred by an electric circuit.

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points, ... more

In electronics, a diode is a two-terminal electronic component with asymmetric conductance; it has low (ideally zero) resistance to current in one ... more

Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is an intrinsic property that quantifies how ... more

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

The drift velocity is the average velocity that a particle, such as an electron, attains due to an electric field. In general, an electron will 'rattle ... more
