I today learn about chrage of electric and Arus/ current electrici? I am not really know in english cause mine is in Malay. I just want to know something that the calculation of Electricity
Charge of electric formula is Q=nq : (C) columba correct me if I am 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 of electrons that 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. I am not really sure wat it mean can some one explain more detail? If I am wrong anything please correct is also. Thx
