Function Of A Resistor In A Circuit

- December 09, 2019

Resistors are used in circuits where excess of current flow might damage the device for eg. Resistors are passive which means they are not affected by the current they carry.

A resistor is functions as a current regulator.

Function of a resistor in a circuit. These resistors are generally of low values so that the over all performance of the circuit is not affected. Resistors manage the current in any electronics circuits. The definition of the resistor is it is a basic two terminal electrical and electronic component used to restrict the current flow in a circuit.

A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. Resistors have two primary functions within a circuit. So a resistor is used to limit the current.

The resistor has a calibrated and known voltage drop and current while the circuit is normal. A resistor in a sensor circuit is used as a simple way to monitor the function of the circuit. A resistor in a sensor circuit is used as a simple way to monitor the function of the circuit.

Resistor set up the proper value of voltage across it due to irdrop. The value of resistors can be expressed in ohms. Some important functions of resistor in electronic circuits is given below.

If there is a short circuit or an open circuit the voltage and current will change and trigger the trouble alarm. The resistor has a calibrated and known voltage drop and current while the circuit is normal. If too much current flows through an led it is destroyed.

When a current flows through a resistor energy is wasted and the resistor heats up. Resistors play an important role to limit the current in any electronic circuits. A resistor is a specialized electrical component that provides resistance as a circuit element.

When a resistor is inserted into a circuit there is a voltage drop across the resistor which in turn regulates the amount of current flowing through the circuit. Resistors are usually made of metal or carbon wire. These devices may provide a permanent adjustable resistance value.

The resistance toward the flow of current will result in the voltage drop. The main function of resistors in a circuit is to control the flow of current to other components. Take an led light for example.

Resistor provides appropriate bias voltage to the active devices. A resistor when introduced in series with the supply terminals of the circuit helps in checking the sudden rise in voltage and averting a possible harm. If there is a short circuit or an open circuit the voltage and current will change and trigger the trouble alarm.

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.
