Connecting in this way helps to reduce or increase the current through the circuit by just changing the position of the moving wiper. Their only drawback is that they have limited resolution. The arrow placed on the resistive strip (arc shaped track), indicates the current position of the wiper terminal. One of the outer pins is connected … thnxxx, what type of phtocell can be used for laser alarm. A variable resistor with a resolution 0.005 means, that the smallest value by which the resistance changes is 0.005 ohm. In a rotary track, some of them may include a switch. It has two terminals and a wiper and works exactly like a variable resistor. of the resistor. Potentiometers are variable resistors commonly used to control the volume on a radio or music system.

As the resistance increases in the variable resistor the current through the circuit decreases and vice versa. This means the relation between the mechanical position and the resistance ratio is logarithmic, when plotted in a graph. If it is a rotary track it is represented in short as LOG, as for a logarithmic track.eval(ez_write_tag([[580,400],'circuitstoday_com-box-4','ezslot_15',110,'0','0'])); A common representation is given below. They are mostly used in high power applications, have a long life and are precise. Potentiometers can be used as voltage dividers. Even more, components are added to this type of a variable resistor so as to make them compatible with complicated electronic circuits.

Definition of Variable Resistor It is an electronic component.

one end of the resistance track and wiper terminal are connected with the circuit, so that the current through the resistor limits according to the position of the wiper contact on the resistance track. Variable Resistor As the wiper is moved across the body of the device, the resistance increases between the wiper terminal and one end terminal and decreases between the wiper and the other end. As the resistance changes, the current changes inversely. When we use the term variable resistor, it means we are talking about linear resistors by default. Variable resistors are mostly used for device calibration. Variable resistors find its application in most of the electronic circuits used today. In recent years, the size as well as the weight of such devices have been greatly reduced which makes it more suitable for any field of electronics.eval(ez_write_tag([[580,400],'circuitstoday_com-leader-1','ezslot_17',113,'0','0'])); Its gives only a basic thing of variable resistors.more detailed specification is useful to clarify. It will decrease. It is applied in an electronic circuit for adjusting circuit resistance to control voltage or current of that circuit or part of that circuit. These resistors offer a different resistance value, which means their resistance values can be adjusted to different values so as to provide the necessary control of current and/or voltage. This when drawn in a graph, will have a straight line with a constant slope. Photo: "Variable resistor" is the very general name for a component whose resistance can be varied by moving a dial, lever, or control of some sort. It is the position of this terminal on the resistive track that decides the resistance of the variable resistor. Since this device is the cheapest among all the three they are more commonly used amongst all of them. A potentiometer can be linear or logarithmic. more clarification about types and characteristics of resistors, cooooooooooooooooooooooooooooool mersi de ajutor, good work… its da perfect answer 2 wat i wanted…..!!! There are mainly three types of variable resistors. One of the critical pieces in an electric circuit, the resistor is the most omnipresent electronic component.
