One of the critical parts that is essential for protecting power supplies is the Power Resistor. Technology has created a range of new electronics and new uses for older parts. One thing every electronic product has in common is that it needs electricity and they often have their own power supply. This does not mean they generate their own electricity, but it takes the available input and converts it to the power and voltage that can be used by the device. This can be in the form of a battery or other source of direct current, or an alternating current source like the one that is available from every wall outlet. The incredible explosion if desktop computers has led to a huge number of devices with critical functions that could be instantly compromised by problems with the electricity and one of these resistors will help stabilize the product and prevent any unfortunate accidents.
There are many new changes everyday in the technology and electronics field. New materials improve the function of important parts and help improve reliability and durability of a range of products. New materials make these resistors better at heat management, which is always a crucial function of the component. However, using special films instead of wires makes it possible for the parts to be designed with different configurations so they can be used in more environments and situations. They are most effective as a passive resistor that acts as a control for the flow of power. One of the issues that has always been a source of research is how to manage the heat that always results from controlling the power.
A resistor is one of the most basic electronic parts and can be used to modify the flow of electricity in a variety of situations. The range of functions and uses they are capable of is mind-boggling. One of the most common ways they work that most people are familiar with is a volume knob. The fancy name for the device is a potentiometer, but most professionals simply refer to them as a pot. They work by decreasing the resistance to a signal as the knob is turned up, resulting in more volume. When the knob is turned down, resistance is increased, the flow of electricity is slowed down, which results in lower volume.
Another interesting use of resistors is in a device known as a thermistor. These devices take advantage changes in resistance in certain materials as the temperature changes. This makes them the perfect choice for electronic thermometers and temperature sensors. The changes in resistance are known so they can be used to get exact readings from remote locations.
