Resistor Function In Physics

Conservation of energy has important consequences here. The resistor is like a pipe that reduces pressure and limits flow because of its resistance.

It is defined by ohms law which says the resistance equals the voltage divided by the current.

Resistor function in physics. Varying resistance changes the amount of current flowing in a circuit. The main purpose of resistor is to reduce the current flow and to lower the voltage in any particular portion of the circuit. A resistor is an electrical component with a known specific value of resistanceit is probably the most common component in all kinds of electronic equipment ranging from a small radio to a colour television receiveras its name suggests a resister resists or opposes the flow of current through itresistance is necessary for any circuit to do useful workin factwithout resistanceevery circuit would be a short circuit.

The voltage source supplies energy causing an electric field and a current and the resistor converts it to another form such as thermal energy. Resistor is defined as. Resistance is a measure of how the flow of electric current is opposed or resisted.

A resistor represents a given amount of resistance in a circuit. User control of circuit functions. Some types of resistors are variable letting you set their resistance by sliding a slider or turning a knob.

Ohms was able to discover a definite relationship between voltage current and resistance. German physicist sir gs. You can for example use a variable resistor to control the loudness of an amplifier the pitch of a musical tone or the speed of a motor.

Resistance is measured in ohms. A passive electrical component with two terminals that are used for either limiting or regulating the flow of electric current in electrical circuits. Basically the function of a resistor is always to oppose the flow of current through it and the strength of this opposition is termed as its resistance.
