Resistor Circuit Definition. A resistor is a passive element in a circuit that provides resistance to the flow of current. The resistance is measured in ohms.
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. The resistance is measured in ohms. There are many different types of resistors such as a thermistor.
The larger a resistor s resistance the greater the barrier against the flow of current.
Resistance is a measure of the opposition to the flow of current in a resistor. In almost all electrical networks and electronic circuits they can be found. In other words it resists the electron flow moving through the circuit. Resistors are all sorts of things light.
