电阻的定义:一电路欲阻止电流通过，同时使电能转换为热能之性质，谓之电阻。电阻单位为欧姆或简称欧，以希腊字母 Ω （ omega ）表示。导体内部有大量 的自由电子，当电压施于导体的两端时，会导致电流的产生，但此一电流不可能 无限制的增加，此乃因为当电荷流经某一材料时，必承受其电阻，此种阻力被消 耗转变成为热能了.在国际单位制中,电阻的单位是欧姆,简称欧,符号是Ω.如果导体两端电压是1伏,通过的电流是1安,这段导体的电阻就是1欧. 导体的电阻是导体本身的一种性质,不同的导体,电阻一般不同;对于同一导体,其电阻大小与加在它两端的电压及通过它的电流大小无关.

导体电阻的大小决定于导体本身的材料、导体的长度、横截面积以及温度等因素.

对同一种材料制成的导体来说,如果它们的横截面积相同,则导体越长,它的电阻越大,长度越短,电阻越小.导体的电阻跟它的长度成正比.

对同一种材料制成的导体来说,如果它们的长度相同,则导体的横截面积越大,它的电阻越小;横截面积越小,它的电阻越大.导体的电阻跟它的横截面积成反比.

The definition of resistance : The electric circuit on the point of stops the electric current to pass ，Cause moreover the electric power transform nature into heat energy ，Resistance which name 。The resistance unit is ohm either abbreviate Ou ，With Greek letter Ω （ omega ）Indication 。There are the greats quantity free electrons internal the conductor ，When tension when Shi Yu's conductor two ends ，Coming into being of electric current be able to be cause ，Yet this electric current can not be unbridled the increase ，This is for serves as that the electric charge runs after when some stuffs ，Certainly stand such resistance ，That this kind of obstruction is used up the transition becoming heat energy is living in the international system of unit , and the unit of resistance is ohm , and abbreviateing Ou , the sign is ΩIn case tension at conductor two ends is 1 dog days , the electric current that passes is 1 ampere , and this length of conductor resistance is 1 Ou .
