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

When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to ... more

The electric power produced by an electric current “ I “ passing through an electric potential (voltage) difference of “ V “

Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is an intrinsic property that quantifies how ... more

The magnetic field generated by the electric current, around a straight wire, is related to the electric current and the distance “r” from the ... more

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

In alternating current circuits, energy storage elements such as inductance and capacitance may result in periodic reversals of the direction of energy ... more

A resistor–capacitor circuit (RC circuit), or RC filter, is an electric circuit composed of resistors and capacitors driven by a voltage or current source. ... more

An electromagnet is a type of magnet in which the magnetic field is produced by electric current. The magnetic field disappears when the current is turned ... 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
