Linear resistor and non linear resistor.

Types of resistor and their definition. Those resistors which values change with the applied voltage and temperature are called linear resistors. They are constructed from a long fine wire usually nickel chromium wire. Blue 6 grey 8 black 0 orange 3 gold 5 the color code value of the above resistor is 68103 68kilo ohms 5.

Varistors are available in a number of forms. They are made of finely divided carbon mixed with a powered insulating. They are mainly categorized on the basis of their applications temperature coefficient tolerance size power reliability voltage etc.

I power type wire wound resistor. Other types of resistor light dependent resistor photoresistor. Power type wire wound resistor is manufactured by winding resistance wire made of nichrome or manganin or constantan and annealed at high temperature to limit the mechanical strain over a ceramic rod as shown in the figure.

To calculate the color code of the above 5 band resistor 5 band resistors consist of colors. When used in dc circuits the potential difference also known as a resistors voltage drop is measured across the terminals as the circuit current flows through the resistor. Types of resistors and their applications wire wound resistors.

Generally there are two types of resistors which have linear properties. Resistors are identified with the help of color codes. High power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls in power distribution systems or as test loads for generators.

As the name indicates thermistors are heat sensitive resistors. In other words a resistor which current value is directly proportional to the applied voltage is known as linear resistors. The resistor of electrical function is specified by the resistance.

There are two types of resistors. They consists of a high grade. Resistor is defined as an electrical component which is used for controlling temperature and voltage.

The different types of resistors are present everywhere in the electronic equipment and in the integrated circuits the resistors are implemented. There are two types such as power type and precision type. A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element.

Light dependent resistors or photoresistors change their resistance. Most types of resistor are linear devices that produce a voltage drop across themselves when an electrical current flows through them because they obey ohms law and different values of resistance produces different values of current or voltage. Resistor finds application in demodulator.

Fixed resistors are the type of resistors which offers a fixed amount of resistance in the circuit. A fixed resistor cannot be changed as it is set at a specific value. 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.
