The wire wound resistor is a type of passive component which is made by winding the metal wire around a metal core. Variable resistors as the name indicates variable resistors have a changeable resistance value.

Different Types Of Resistors With Pictures Function And Uses

Resistors are mainly of two types and can be either of fixed or variable value.

Types of resistor in physics. Thermistors are a type of variable resistor which notices the change in temperature. Hence the metal wire restricts the electric current to certain level. The different types of fixed resistors include.

In other words thermisters is a type of variable resistor which notices the change in temperature. There are several types of nonlinear resistors but the most commonly used are mentioned below. Three 15 ohm resistors connected in parallel are equivalent to one 5 ohm resistor.

Resistor is defined as an electrical component which is used for controlling temperature and voltage. There are two types of resistors. Resistor finds application in demodulator.

The resistance of a thermister is inversely proportional to the temperature ie. The metal wire acts as the resistive element to the electric current. The resistance of a thermistor is inversely proportional to the temperature.

Thermisters are made from the cobalt nickel strontium and the metal oxides of manganese. Resistance increases when temperature decrease and vice versa. Resistors are identified with the help of color codes.

Across a 30 volt battery that 5 ohm resistor will pass 6 amperes and dissipate 180 watts. So each of the 3 resistors will conduct 2 amperes of current and dissipate 60 watts of heat. The various types of fixed resistors include carbon composition carbon film carbon pile metal film metal oxide film wire wound thick and thin film and grid resistor.

Linear resistor and non linear resistor. In other words it is a 2 terminal device which is very sensitive to temperature.
