The meaning of RESISTANCE is an act or instance of resisting : opposition. How to use resistance in a sentence.
The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction.
Electrical resistance is defined as the property of an electrical component to resist the flow of electric current. The unit of electrical resistance is ohm which is defined as volt per ampere.
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
Review the key terms, equations, and skills related to current, resistance, and resistivity, including how to find the current direction and what resistance depends on.
May 30, 2024 · Resistance, in electricity, property of an electric circuit or part of a circuit that transforms electric energy into heat energy in opposing electric current. Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductors.
We now consider the resistance of a wire or component. The resistance is a measure of how difficult it is to pass current through a wire or component. Resistance depends on the resistivity.
