What is a Variable Resistor?Variable resistor definitionResistor whose resistance can be adjusted as needed. It is a common component in electronic circuits that allows current or voltage to be adjusted according to Ohm's law.Basic structure of variable resistorA variable resistor usually has three terminals: two fixed terminals at the end of the resistance track and one removable terminal (cursor). Depending on how the terminals are connected to the circuit, a variable resistor can be used as a
