Energy density is the amount of energy stored in a given system or region of space per unit volume or mass, though the latter is more accurately termed ... more

According to Hooke’s Law, Elastic potential energy is stored in a simple harmonic oscillator at position x,for example, the energy saved in an object ... more

If two or more components are connected in parallel they have the same potential difference (voltage) across their ends. The potential differences across ... more

Electrical resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor and depends on: What ... more

If two or more components are connected in parallel they have the same potential difference (voltage) across their ends. The potential differences across ... more

In a series configuration, the current through all of the resistors is the same, but the voltage across each resistor will be in proportion to its ... more

A regenerative brake is an energy recovery mechanism which slows a vehicle or object by converting its kinetic energy into a form which can be either used ... more

In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input ... more

Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are called series and parallel ... 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
