Current gain - simplified formula (for equal impedances)

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

Electric current (AC)

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

Bipolar junction transistor (Common-emmiter current gain )

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

Load and Resistance Factor Design (LRFD) - Load combinations (eq4)

In structural engineering, a structure is a body or combination of pieces of rigid bodies in space to form a fitness system for supporting loads. ... more

Current (AC-rms)

The RMS current for sinusoidal systems can be described mathematically as a function of peak current.

Solar Rotation

Solar rotation is able to vary with latitude because the Sun is composed of a gaseous plasma. The rate of rotation is observed to be fastest at the equator ... more

Peukert's law

Peukert’s law, presented by the German scientist Wilhelm Peukert in 1897, expresses the capacity of a battery in terms of the rate at which it is ... more

Magnetic force (between parallel conductors)

In magnetostatics, the force of attraction or repulsion between two current-carrying wires is often called Ampère’s force law. The ... more

Adjusted current yield

The current yield, interest yield, income yield, flat yield, market yield, mark to market yield or running yield is a financial term used in reference to ... more

Coil magnetic energy

The magnetic energy stored by a coil carrying a current is given by one half of the inductance of the coil times the square of the current
