The Townsend discharge is a gas ionization process where free electrons, accelerated by a sufficiently strong electric field, give rise to electrical ... 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

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

Admittance is a measure of how easily a circuit or device will allow a current to flow. It is defined as the inverse of impedance. Admittance, just like ... more
