I today learn about chrage of electric and Arus/ current electrici? Im not really know in english cause mine is in Malay. I just want to know something that the calculation of Electricity(adsbygoogle = window.adsbygoogle || []).push({});

Charge of electric formula is Q=nq : (C) columba correct me if im wrong.

A electric current( not sure right pronounsation) formula is I=Q/t

Example question that i want to ask y this happens.

A charge if electric is 1 x 10^-9 C

Find the number ofelectronsthat flows every second ( i want to find how many electrons flows every 1 second)

Answer :

Q/t=nq/t

I = nq/t

I/q = n/t

(1 x 10^-9) / (-1.60 x 10^-19) = n/t

n/t = 6.25 x 10^12 <----- It should be ( -6.25 x 10^12)

but y izzit positif? I learn that if you count amount of electron in a object then its suppose to be neagatif as answer? My teacher said something about science term that there is no negatif value. Im not really sure wat it mean can some one explain more detail? If im wrong anything please correct is also. Thx
