What is passive resistor?

A passive resistor is a two-terminal electrical component that resists the flow of electric current, converting electrical energy into heat without producing any energy itself. It follows Ohm's Law, where the voltage across the resistor is proportional to the current flowing through it. Passive resistors are commonly used in circuits to control current and voltage levels, as well as to divide voltages. Unlike active components, passive resistors do not have the ability to amplify signals or provide power gain.
