.ResistorA resistor is a two-terminal electronic component that opposes an electric current by producing a voltage drop between its terminals in proportion to the current, that is ,in accordance with Ohms law :V=IR .The electrical resistance R is equal to the voltage drop V across the resistor divided by the current I through the resistor. Resistors are used as part of electrical networks and electronic circuits.电阻器是一个二端口电子元件,电阻是阻止电流流动，通过按比例产生其端子之间的电压降的电流,也就是说,根据欧姆定律:V = IR。电阻R等于电压降V除以通过电
