First proposed by Clement D. Child in 1911, Child’s law states that the space-charge limited current (SCLC) in a ... more
A solenoid is a coil wound into a tightly packed helix. In physics, the term refers specifically to a long, thin loop of wire, often wrapped around a ... more
Connected in series, the capacitors each store instantaneous charge build-up equal to that of every other capacitor in the series. The total voltage ... more
A bipolar junction transistor (BJT or bipolar transistor) is a type of transistor that relies on the contact of two types of ... more
In mathematics, the gamma function (represented by the capital Greek letter Γ) is an extension of the factorial function, with its argument shifted down by ... more
The constant K_v (motor velocity constant, or the back EMF constant) is a value used to describe characteristics of electrical ... more
Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to produce electrical power, windmills for mechanical ... more
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the ... more
In physics, the wavelength of a sinusoidal wave is the spatial period of the wave—the distance over which the wave’s shape repeats, and the inverse ... more
