What are the types of resistors
• Resistor as an indispensable element in our circuit, without which you may not be able to control the current, your product is difficult to execute, so do you know how many types of resistor?
• Since why is a resistor to make various types of resistors, the main reason because different materials will have different electrical conductivity and temperature resistance, cost is different, in order to apply to a variety of product requirements, so there are a variety of products, today we will discuss the different resistors, it is suitable for those application scenarios, at the same time can meet your selection demand and resistance purchasing demand.
Types of resistor
• Our most common types of resistors are these as well as their shape shapes.
| Thick film resistors |  |
| Chip resistor |  |
| Alloy resistance |  |
| Wire resistance |  |
| NTC thermal resistor |  |
| Plastic seal patch varistor |  |
| Plug-in pressure sensitive resistance |  |
| Oxide membrane resistance |  |
| Exclusion |  |
| PTC thermal resistor |  |
| Deposited-carbon resistor |  |
| Porcelain pipe resistance |  |
| Light dependent resistors |  |
| Aluminum shell resistance |  |
| Precision potentiometer |  |
| Adjustable resistor |  |
Different types of resistor
Different resistors because of different material it is destined to be different, it came to the world with different mission, some is closely related to temperature, some ordinary everywhere courseware, some help us adjust all kinds of circuit, so what is resistor used for？the application field of resistorsso？ we are to discuss in detail under the resistors.
• Fixed Resistor:The most widely used can be said to be theFixed Resistor, its characteristic is that the resistance value can not be changed through external intervention, what the resistance value is fixed, carbon film, metal film or metal oxide film is its main material, electronic equipment, communication equipment and PC mobile phone will use this kind of resistance.
• Variable Resistor:Variable Resistor, through its name can guess its function.It is a kind of resistor that can manually or automatically adjust its resistance value, of course, it was invented because there are some specific areas that need this kind of resistor that can adjust its function, such as the tuning platform in audio equipment, medical detection or optical instruments, analog instruments and so on.
• Thermal Resistor:There is a resistance is born for temperature, is theThermal Resistor， its resistance will change when the temperature change, because some areas also need this type of resistivity, she is mainly used in temperature measurement, temperature protection temperature compensation, etc., with temperature related areas, so it is born for temperature, and, without it, may home rice cooker temperature control, or air conditioning temperature car temperature detection has become a problem.
• NTC Resistor:There is a Resistor and Thermal Resistor is mutually compensatory, that is the NTC resistance, is a ─ negative temperature coefficient resistance, resistance value with the rise of temperature and decline.Our common thermometer can be used, as well as in a thermostat or any circuit that requires temperature compensation.
• Light Dependent Resistor (LDR):Thermal Resistor conquered the temperature, then let the LDR to conquer light， naturally those related to the light related fields will find Light Dependent Resistor (LDR), such as light control light, light circuit or the need to adjust the external light and other related circuits. Its main materials are selenization, vulcanization and so on.
Why do we use resistors in a circuit
• why do we need resistors？ Because they allow us to control the flow of electrons and currents so we can make the material run how we want it to, why are resistors important?
• We all know that everything is based on energy control, and the current is energy, to control the current means that we can control all the electronic products, so this is why we need the main reason for the resistance in the circuit, how does a resistor work, understand that we can let it do more things in our circuit.
Resistance examples in real life
• Many people still cannot fully understand the working principle of resistance, we can, for example, is in life, we need to control the size of the water in the pipe, we only need to do the pipe, to the water, don't flow so fast, or according to our will to control the size of the water, so back to the resistance, the current is water, and resistors is need to increase to the resistance, the only difference is the resistance needs to consume excess current electricity, so will be converted into heat, this is the main reason why resistance heat.
• Of course, you can solve this problem by understanding the Temperature Coefficient of Resistance-Meaning and calculate.
• We all know that everything is based on energy control, and the current is energy, to control the current means that we can control all the electronic products, so this is why we need the main reason of the resistance in the circuit, how does a resistor work, understand that we can let it do more things in our circuit.
What is an example of a resistor
• The piezoresistor is the bane of lightning：Thunder and lightning, thunder and lightning will reach TV by outdoor antenna, may bring risk, this time only need small two piezoresistor will be able to protect your TV, the reason is that when the voltage within the nominal value, the piezoresistor value present infinite state, almost no current through, so it is the property of the isolation current a good choice.
• The LED lights will adjust the brightness：LED lamp is energy-saving and environmental protection lighting products, its brightness can be adjusted by the resistor, see here everyone knows that the basic function of the resistor is to control the size of the current, the most basic function is enough to control the LED until the brightness.This is a typical application scenario.
