In electronic circuits, resistors are used to reduce current flow, adjust signal levels, divide voltages, bias active elements, and terminate transmission lines, among other uses. A resistor opposes the flow of electrical current; the higher the value of the resistor, the more it opposes the current flow. Values are given in ohms. Thank you for your support!
