Resistors are passive electrical devices that resist the flow of an electrical current. The voltage across and the current through a resistor are related by Ohm’s law. Unlike capacitors and inductors, the resistance of a resistor does not change with its frequency. The amount a resistor constricts the flow of a current is its resistance. ‘Thru-hole’ resistors are labeled by their resistance using a color band scheme.
