Generated at the center of a circular wire by the electric current, related to the electric current and the distance from the wire to center of the circle.

A bipolar junction transistor (BJT or bipolar transistor) is a type of transistor that relies on the contact of two types of ... more

The voltage of one of the two nearby coupled inductors

The magnetic field generated by the electric current, around a straight wire, is related to the electric current and the distance “r” from the ... more

Capacitance is the ability of a body to store an electrical charge. Any object that can be electrically charged exhibits capacitance. Capacitance is a ... more

The power gain can be calculated using voltage instead of power using Joule’s first law to calculate a voltage gain. In many cases, the input and ... more

The series RLC can be analyzed for both transient and steady AC state behavior using the Laplace transform. If the voltage source ... 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

In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance, dark ... more
