The two ends of the coax cable-branching is not allowed-are fitted with terminating resistors that regulate the electrical properties of the cable so signals propagate throughout the length of the cable but don 't reflect back .
The circuit has several " ballast " resistors that limit the discharge 's current so that the flashlight is safe to touch .

Paul romano , chief operating officer of fusion trade inc. , an andover , mass . - Based company that buys and sells electronic components , said a significant amount of components like capacitors and resistors are made in japan .
Over the years , the resistors , capacitors , and transistors on silicon chips have gotten smaller and smaller , but with each subsequent generation , it becomes more difficult to find ways to shrink them further .
年复一年,硅芯片上的电阻、电容和晶体管被做得越来越小,但随着逐代推进,继续缩小尺度变得越来越难。
Similarly , if an electrical engineer draws a circuit diagram , the software will identify the circuit 's separate components - like resistors , capacitors , batteries , and simple wires - and display them in different colors .
