Definition Of Resistance And Resistor
It is an electronic component.
Definition of resistance and resistor. A resistor is a passive element in a circuit that provides resistance to the flow of current resistance is a measure of the opposition to the flow of current in a resistor. Resistor definition a device designed to introduce resistance into an electric circuit. The resistance can be calculated with ohms law when the current is known and the voltage drop is measured. Resistance definition is an act or instance of resisting.
The function of a resistor is to oppose the electric current through it. It obstructs or blocks the flow of electric current flowing through the circuit. The larger a resistor s resistance the greater the barrier against the flow of current. The electrical resistance is varied by sliding a wiper contact along a resistance track.
Basically the resistance of the resistor is the energy dissipated by the resistor when the current flows through it. A resistor is the basic component of electrical and electronic circuits. The resistance of a resistor is dependent on its material and shape. This is called electrical resistance and is measured in the unit ohm.
Resistor synonyms resistor pronunciation resistor translation english dictionary definition of resistor. Resistance of a resistor. Definition of variable resistor. In electronic circuits resistors are used to reduce current flow adjust signal levels to divide voltages bias active elements and terminate transmission lines among other uses high power resistors that can dissipate many watts of electrical power as heat may be used as.
In electrical engineering electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit. Sometimes the resistance is adjusted at preset value as required at the time of circuit building by. Resistor definition is a device that has electrical resistance and that is used in an electric circuit for protection operation or current control.
A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. A device used to control current in an electric circuit by providing resistance.
