What is the difference between PTC and NTC resistors?
positive temperature coefficient vs. negative temperature coefficient resistance increases or decreases with increase of temperature, respectively.
What is the working principle of the thermistor?
A thermistor changes it's resistance depending on temperature. Hence Thermal-Resistor. (Thermistor) It is all to do with the crystal structure of the substance the thermistor is made of. Some increase their resistance as temperature rises, called Positive Thermal coefficient, 'PTC'. Others reduce their resistance with increasing temperature, called Negative Thermal Coefficient. 'NTC'. They can be used in a feedback loop of a simple amplifier and switch circuits, to control temperature of a device. They can be calibrated for use in a current loop, to directly measure temperature, like a thermometer. They can be used to stop surges in start up circuits, initially giving a high resistance until things warm up. Or used to apply a large current and then reduce as things warm up. (Like in the old degaussing coils on a colour CRT).

What is height of sharry maan a Punjabi singer?
itni jada hai k main bata hi nahi sakta mere khayal se his height is 5'6' bcoz when he is standing nearby diljit dosanjh in ptc punjabi music awards he is only a little bit shorter than diljit whose height is approx 5'8' i can say this bcoz i saw him when he came to pacific mall in delhi
What is the best selling CAD program in the world?
This depends on the type of CAD (2D or 3D) - and how you count the seats and maintenance payments... but the big players are: Autocad by Autodesk - best-selling 2D CAD package, used all over the world in most industries Pro/E by PTC - popular 3D CAD package Solidworks - fast-growing 3D CAD package CATIA, Unigraphics, Inventor, SolidEdge and others are also available
Is a NTC thermistor different from PTC thermistor?
Yes, NTC stands for Negative temperature coefficient. This means the resistance goes down as temperature goes up. A PTC has a positive temperature change. As temp goes up, the resistance will increase also.
Fullform of ntc and ptc?
ntc: negative temperature coefficient ptc: positive temperature coefficient
What is the difference between ntc and ptc?
NTC is resistance decreases as the temperature increases. NTC are made up of metal oxides from elements such as iron, copper, manganese, nickel and titanium. NTC are very reliable and can operate accurately at relatively high temperatures. NTC are uses in thermostats, ovens, engines and laboratory, industrial and manufacturing processes. PTC resistance increases as the temperature increases. PTC is many applications that benefit from their temperature measuring capabilities. PTC is semi conductive resistors made from polymers or polycrystalline ceramic materials. PTC are used in apparatuses such as motors and self-regulating heaters, and in time-delay, liquid level and air-flow equipment. PTC will offer the amount of resistance required to regulate temperatures or limit currents, therefore protecting the application from damage.
Why does the resistance of a thermistor change when you change its temperature?
The resistance of a thermistor changes when its temperature changes due to the inherent properties of the thermistor material. In a negative temperature coefficient (NTC) thermistor, the resistance decreases as the temperature increases, whereas in a positive temperature coefficient (PTC) thermistor, the resistance increases as the temperature rises. This change in resistance is caused by the variation in the number of charge carriers (electrons or holes) and their mobility within the material as temperature changes.
What is an application for a positive temperature coefficient ptc thermistor device?
A positive temperature coefficient (PTC) thermistor is commonly used in overcurrent protection applications, such as in electrical circuits and power supplies. When the temperature rises due to excessive current, the resistance of the PTC thermistor increases sharply, limiting the current flow and preventing damage to the circuit. Additionally, PTC thermistors are utilized in heating applications, such as self-regulating heating elements, where they provide consistent temperature control by adjusting resistance with temperature changes.
What is the difference between PTC and NTC resistors?
positive temperature coefficient vs. negative temperature coefficient resistance increases or decreases with increase of temperature, respectively.
What does PTC stand for?
PTC stands for "Positive Train Control," a technology used in the railroad industry to automatically control train movements and prevent accidents by monitoring and controlling train speed, movement authority, and adherence to signals.
How do you test motor thermal protection relay?
The thermistor motor protection relays CM-MSE, CM-MSS and CM-MSN are used to control motors equipped with PTC temperature sensors. The PTC temperature sensors are incorporated in the motor windings to measure the motor heating. This enables direct control and evaluation of various operating conditions. Depending on the products also ATEX approvals for use in hazardous areas are available.
How does a thermistor effect the resistance of the temperature?
A thermistor is a type of temperature-sensitive resistor whose resistance changes significantly with temperature variations. Specifically, negative temperature coefficient (NTC) thermistors decrease in resistance as temperature increases, while positive temperature coefficient (PTC) thermistors increase in resistance with rising temperature. This property allows thermistors to be used in temperature sensing and control applications, enabling precise monitoring and regulation of temperature-dependent processes. Their sensitivity makes them suitable for various electronics, including temperature sensors and circuit protection devices.
What does a ptc relay do?
A PTC (Positive Temperature Coefficient) relay is an electronic component that uses a positive temperature coefficient thermistor to control electrical circuits. As the temperature increases, the resistance of the PTC device rises sharply, which can interrupt the flow of current and protect circuits from overcurrent conditions. When the temperature drops, the resistance decreases, allowing current to flow again. This makes PTC relays useful for applications requiring thermal protection and resettable fuses.

What is a PTC Relay?
A PTC relay, also known as a positive temperature coefficient relay, is a type of protective device used in refrigerators and air conditioners to protect the compressor from overheating. It uses a thermistor that increases its resistance with temperature, helping to regulate the current flowing to the compressor and prevent damage.
