the measure of electric potential difference between two points in a circuit, expressed in volts

an electrical component designed to limit or control the flow of electric current in a circuit, typically by providing resistance

the complete circle through which an electric current flows, typically consists of the source of electric energy

a phenomenon where certain materials conduct electricity without resistance when cooled to extremely low temperatures

to apply an electric charge to a conductor

a form of electricity generated by friction between two materials, resulting in an imbalance of electric charges on their surfaces

(of a battery or device) capable of being supplied with electrical power again

a machine that produces electricity by converting mechanical energy into electrical energy

a positively charged electrode in an electrical device where oxidation occurs, resulting in the release of electrons

a negatively charged electrode within an electrical device, from which electrons flow out into the external circuit

a device that converts the energy of the sun into electricity

the energy transmitted in the form of particles or waves through the space or a matter

related to the technology that turns sunlight directly into electricity

referring to the combined interaction of electric and magnetic fields, often associated with waves or radiation

an invisible area around a magnetic object where magnetic forces can attract or repel other objects

a long rigid bar that is put under a heavy object in order to move it

a point or support on which a lever pivots or rotates in order to lift or move objects

the rapid back-and-forth movement of an object

a rotational force measured in newton-meters or foot-pounds

a mass used to provide balance to another mass

having a speed greater than that of sound

(physics) the increase in velocity over time

the constant speed reached by a falling object when the drag force equals the gravitational force pulling it downward, resulting in no further acceleration

a branch of science and engineering that deals with the mechanical properties of liquids, particularly their behavior in confined spaces and under pressure

(physics) the universal force of attraction between any pair of objects with mass
