邊個有最高電阻?
發問:
最佳解答:
Assume that each piece of material is of the same dimensions and subject to the same voltage. Then by Ohm's Law, Resistance = voltage/current or resistance of the material is inversely proportional to the current that passing through it. It is thus apparent that the resistance of material Y is highest, followed by material X, and material Z hs the least resistance. Material Y can thus regarded as an insulator under the applied voltage.
其他解答:
根據歐姆定律，電流同電阻成反比，所以Y嘅電阻原理上係無限大，但電阻大小隨著施加電壓大小而改變。

1) 物料X, Y, Z 邊個有最高電阻? 電流---- x : 0.1A, Y: 0A, Z: 2A 其實Y係咪insulator? 咁算5算有最高電阻??最佳解答:
