Ohm's Law

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

Heat flow in electronics - maximum power dissipate

The heat flow can be modelled by analogy to an electrical circuit where heat flow is represented by current, temperatures are represented by voltages, heat ... more

Inductors in Parallel

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

Potentiometer Voltage Divider

Potentiometer is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider. The potentiometer can be used as a voltage ... more

Voltage AC (3-phases)

AC 3-phases sinusoidal voltage (rms – root mean square) for a triangle waveform centered about zero, can be described mathematically as a function of peak ... more

Vacuum tube - transconductance

In electronics, a vacuum tube, an electron tube, or colloquially a tube (North America) or valve (British usage), is a device that controls electric ... more

Hall voltage (Hall effect)

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

Resistances connected parallel

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

Electric Potential Energy with Time (related to Electrical Work)

Electrical work is the work done on a charged particle by an electric field. The equation for 'electrical’ work is equivalent to that of ... more
