What is difference between varistor and thermistor?

is that varistor is an electronic component having a variable resistance; used to protect circuits against power surges while thermistor is a resistor whose resistance varies rapidly and predictably with temperature and as a result can be used to measure temperature.

How is thermistor different from resistor?

As nouns the difference between resistor and thermistor is that resistor is one who resists, especially a person who fights against an occupying army while thermistor is a resistor whose resistance varies rapidly and predictably with temperature and as a result can be used to measure temperature.

What is a thermistor resistor?

A thermistor is a resistance thermometer, or a resistor whose resistance is dependent on temperature. The term is a combination of “thermal” and “resistor”. It is made of metallic oxides, pressed into a bead, disk, or cylindrical shape and then encapsulated with an impermeable material such as epoxy or glass.

Why to I use a resistor with a thermistor?

A thermistor is a temperature sensitive resistor. They are often used as a temperature sensor. Unlike most other resistors, thermistors usually have negative temperature coefficients (NTC) which means the resistance decreases as the temperature increases.

Can I replace a thermistor with a varistor?

Just change the placement of thermistor and varistor can solve the problem simply. If use the recommended circuit(thermistor place before varistor),there must be using higher level thermistor for take the surge test.

What is MOV capacitor?

A Metal Oxide Varistor (MOV) is a protection component used in power supply circuits that is powered directly from AC mains. It is used to protect the circuit from high voltage spikes by varying its resistance.

What resistor does thermistor use?

NTC thermistors are the most commonly used (especially the 10KΩ NTC thermistor) and along with an addition series resistor, RS can be used as part of a simple potential divider circuit. Thus changes to its resistance due to changes in temperature, produces a temperature-related output voltage.

Is a thermistor a fixed resistor?

Fixed resistor is a type of resistor that only restricts the flow of electric current but does not control (increase and decrease) the flow of electric current. This special type of resistor is called thermistor.

What is the difference between fuse and varistor?

Unlike the fuse or circuit breaker which offers over-current protection, the varistor provides over-voltage protection by means of voltage-clamping in a similar way to the zener diode. In many ways the varistor looks similar in size and design to a capacitor and is often confused as being one.
