自由電子=電荷嗎?

自由電子=電荷嗎?若等於,可但一庫倫的電荷約等於600億億粒電子,自由電子不就是電子嗎?

Electrons are particles that carry negative charge. The charge carries by an elecro is -1.6x10^-19 coulombs.

Thus free electron is NOT equal to charge.

若不等於,但電子的單位又是庫倫,這麼一庫倫自由電子又等於什麼?

This sentence [電子的單位又是庫倫] is incorrect. Electrons exist in individual particles. The coulomb (庫倫) is a unit for charge (電苛).

不如叫你父母比錢你補習啦,係到比人教錯你就唔好

Your make some mistakes, electrons do have charge (電荷), even they are free or not, an object carrying charge(s) does not mean it is carry (free) electronic(s) or not. Say holes (positive charge with effective mass same as electron), positron (anti-particle of electron), or just simply proton (same charge value but oppsite sign, 1 electron charge = -1.6 x 10^(-16)C, while 1 proton carry 1.6 x 10^(-16)C ).

1C of free electron charge is simply a number of electrons with total charge 1C, that's all, nothing else.

C was used before the discovery of electron, it is a unit to measure charges. Same as A (ampere, 1A=1C/s, 1 C per second), it was used long long time ago in electric.

C is used for all charges, it is not electron, but electrons do carry charges.

Maybe it is not clear for using english to answer this question. C is the unit to measure charges, charge is not C, C is a measure of how many charges there.

C is a unit same as kg, where kg is a measuremnet of how heavy the mass is, but it is not mass itself. You can use kg, lb, amu and etc to tell how heavy the mass is. This is the same as the case of C.

自由電子/電子所戴住的是電荷/電量,就等於人戴住錢.但人不等於錢.

自由電子是電子,但電子可分自由同不自由,so電子不等於自由電子.

正因自由電子是電子,so都戴住電荷.@而電荷單位是庫倫.@

***不是電子單位是庫倫,電子是以粒做單位***


庫倫同打一樣.一打筆十二,一打蛋都係十二.

所以,一庫倫電荷等於600億億粒电子所戴的电荷量.
