A resistor is a type of electrical component that is comprised of two terminals that help to create voltage that is relative to the electricity passing through it. Voltage is the specific type of power that will cause current to actually flow within a circuit. Resistance, which is where resistors get their name, is measured in Ohms and controls the current electrical flow. The currents' flow has to be regulated to make sure that the electrical parts and components are all going to be able to function as they were meant to.

In reality, there are actually a lot of different types of resistors that are out there. Carbon resistors are one example and they are used by attaching leads to carbon material. This is a type of resistor that is not usually going to be that expensive. In addition to this, carbon resists cannot dissolve that much power, so that is something that is important to know if you are choosing this type of resistor for your project.
Many people are looking for resistors that have better tolerances. These types of resistors are going to be the ones that have metal oxides or films. The most common type of resistor that people can use for a variety of things is the wirewound resistor. This dissipates large levels of electricity when you compare it with other resistors that are out there and is made with a tight tolerance, but also can help to control temperatures really easily. Wirewound resistors are great for someone that is looking for precision, which is a big part of the reason that a lot of the more modern circuits that you might find will use this type of resistor.
No matter what type of resistor you are actually using, you have to know the power rating and the voltage rating. You also should pay close attention to the tolerance and resistance. All resistors are different and have positive and negative things about them depending on the type of project they will be used for. Since an electrical component is only going to be as good as the parts that are in it, you have to find high quality resistors to help you make up the circuit.

Something else that you may want to think about as you are shopping for a resistor, whether it is custom made or generic, is the parts within it. You want to make sure that they are RoHS, which stands for Restriction of Hazardous Substances. They should not have a lot of specific types of materials in them, such as mercury or cadmium, because it can cause them to become dangerous.
