Trade Assurance. Variable resistors are electrical components that give you control over the current flow through an electric circuit. The circuit is … This is because output devices with a specific name is used everywhere instead of it. To figure out what is a load resistor  in detail you should know about the term load, where it came from? Load Banks and Variable Resistors . A variable resistor is used because a potential divider with 3 terminals is known as a potentiometer. What if we use a very small load in the power/electrical circuit? Order : 100 Pieces Variable Load Resistor . Clear All. iii) Inductive load: The load connected in the circuit which is inductive can be termed as inductive load. Thus, the current IL flowing through the load resistor RL (the potentiometer) is: IL = 1.25 V / (R + RL). Uff IR, • What Is The Value Of Lo That Power Dissipated In The Load Is The Highest? Established in 1983, We "Enapros" are a Manufacturer, Exporter and Importer of Electrical Resistor, Load Bank, Resistance Boxes, Housed Chassis Mounted Wire, Edge Wound Resistor, Aluminum Braking Resistor and many more.With improved technology developed over the years. So today we have discussed in detail the voltage divider formula from where it comes from where the formula is derived along with some practical example. A precision resistor is a normal resistor with near accurate ohmic values. As the name suggests, variable + load + resistor. Variable resistors come in many shapes and sizes. I have to modelize a tramway line. Additionally, in practical circuits, there is nothing like a load resistor. It generally consists of an electro-mechanical transducer. The lower the value of tolerance of the resistor shows the lower deviation from resistor value and higher the value of tolerance the higher the […], Insertion loss and return loss are widely used terms in the field of microwave technologies. The ballast acts, therefore, as a variable load on the system, differing from "load resistors" which have a constant resistance. It also recognized as a discharge load resistor, this type of device has its application in discharging the stored energy in the output capacitor to avoid electric shock or damage of output devices. Browse our wide range of variable resistors including potentiometers, rheostats and thermistors from market leading electronics brands including Vishay, Bourns, EPCOS and RS Pro.
