An electrical device used to store electrical charge. 2012 UL LLCThe appearance of a company's name or product in this database does not in itself assure that products so identified have been FOWX8.E184650 rs, Antenna-coupling Components, Line-bypass 2011 Underwriters Laboratories Inc. resistors. A resistor, like batteries and lights, can also be present in an electrical circuit. A resistor limits the flow of electricity in the circuit. Like rocks in a pipe that slow the flow of water, a resistor will limit the flow of electricity. A variable resistor is made of a piece of metal that can change in length. As the length of the resistor changes, so does the resistance in the same direction. . Transistors, Cable Impedance. diode bridge. Lecture 8: Electronics. UCSD Physics 122. 2. Basic Circuit Analysis.
