In finance, the capital asset pricing model (CAPM) is used to determine a theoretically appropriate required rate of return of an ... more

A mechanical joint is a part of a machine which is used to connect another mechanical part or mechanism. Mechanical joints may be temporary or permanent. ... more

Concrete has relatively high compressive strength, but significantly lower tensile strength. As a result, without compensating, concrete would almost ... more

Security characteristic line (SCL) is a regression line, plotting performance of a particular security or portfolio against that ... more

An isothermal process is a change of a system, in which the temperature remains constant: ΔT = 0. This typically occurs when a system is in contact with an ... more

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

The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable ... more

In the simplest case a common collector transistor (emitter follower) is used with the base of the regulating transistor connected directly to the voltage ... more

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