If the flowing current through a resistor change with the applied voltages then it is called a varistors or vdr voltage dependent resistors.

What are non linear resistors. In this resistor the resistance varies with temperature. Basic electronics non linear resistors thermistor. In this resistor the resistance varies with light.

The property exhibited by devices whose resistance does not change uniformly with changes in voltage or current. Ntc resistors figure a negative temperature co efficient their resistance lowers with temperature rise. Ptc resistors figure b positive temperature co efficient their resistance increases with the temperature rise.

In addition if the flowing current through a resistor changes with change in body temperature then these kinds of resistors are called thermisters. Non linear resistors are those whose current does not change linearly with changes in applied voltage. In other words a resistor which current value is directly proportional to the applied voltage is known as linear resistors.

Those resistors which values change with the applied voltage and temperature are called linear resistors. Thermistors are a type of variable resistor which notices the change in temperature. The resistance of a varistor varies with the applied voltage.

There are many different types of resistors. These resistors vary in their construction power dissipation capacities and tolerance to various parameters such as temperature and light. There are several types of nonlinear resistors but the most commonly used include.

Types of non linear resistors. It is so because the current flow always results in production of heat which either increases as in metals or decreases their resistance as in insulators. Many different devices have characteristic curves i v plots that are not straight lines and they are therefore not linear devices.

A resistor is a passive component in a circuit which provides resistance to the flow of current. Non linear resistors are devices that respond to external stimuli in order to create a desired outcome for a circuit. A varistor is a nonlinear resistor made of semiconductor.
