Resistor Circuit Definition. A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. In other words it resists the electron flow moving through the circuit.
In an electrical circuit a resistor passively opposes the flow of current. An ohm is the resistance that occurs when a current of one ampere passes through a resistor with a one volt drop across its terminals. In other words it resists the electron flow moving through the circuit.
There are many different types of resistors such as a thermistor.
In almost all electrical networks and electronic circuits they can be found. In an electrical circuit a resistor passively opposes the flow of current. Resistor definition is a device that has electrical resistance and that is used in an electric circuit for protection operation or current control. A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.
