EVERYTHING ABOUT RESISTANCE FROM A TO Z
What are the Usage Areas of Resistors?
In electrical circuits, the opposition encountered by electric current through a conductor is called resistance. The properties of resistance, expressed in Ohms, are similar to mechanical friction. Systems represented by the letter R in equations have two different symbols. Resistors, which help maintain the current at a specific value in electrical circuits, prevent high current from passing through particularly sensitive circuit elements with these properties. All types that can be used in many areas of industry can be found in online electronics stores such as .
Options that also enable the control of physical changes in the external environment can prevent high current from passing through sensitive circuit elements. At the same time, options used for dividing current and supply voltage can be found in different types. With types like PTC, LDR, and NTC, it is also possible to benefit from the heat generated when the current falling on them increases.
Reading and Calculating Resistance
Resistor options, which can be used in a wide variety of fields, vary depending on the area of use. An example of systems found in all electronic circuits is the use of adjustable resistors like potentiometers in controlling output signals, such as in dimmer circuits. Another example of resistance differences is LDR type resistors. These types act as sensors and function in light-sensitive circuits. Another type, NTC-PTC thermistors, are used in heat-sensitive circuits. These options react according to the heat applied to them. Ohm's law is used to calculate resistance. To perform the calculation correctly, the voltage across a two-terminal circuit element must be divided by the current passing through the element. After calculating the values, they can be distinguished by coloring. In options represented by black, brown, red, orange, yellow, green, blue, violet, gray, white, gold, and silver colors, each color represents a specific range.
