A resistor is a component that, despite its size, offers some appreciable resistance to the flow of electric current. It acts as a hindrance to the motion of electrons within the circuit.
In the context of electric circuits, a resistor is a passive two-terminal component designed to impede the flow of electric current. It introduces resistance, measured in ohms (Ω), regulating the current according to Ohm’s law (V = IR). Resistors are crucial for controlling voltage levels, limiting current, and dividing voltages in circuits. They come in various types, including fixed and variable resistors, and are used for tasks like protecting components, setting bias points, and shaping signal waveforms. Resistors play a fundamental role in adjusting the behavior of electronic circuits to meet specific design requirements.
