Question

Which of the following describes electric current?
A. Electric current is the flow of protons
B. Electric current is the flow of neutrons
C. Electric current is the flow of a charge
D. Electric current is the flow or protons and neutrons
D?...

Answer 1

Not D. Neutrons have no charge and both neutrons and protons are trapped in the nucleus of the atom. They cannot flow.

Answer 2

so C?

Answer 3

C. Electric current is the flow of a charge

Answer 4

Yes, it is flow of charge

Answer 5

protons and neutrons don't move or flow

Answer 6

except in nuclear reactions

Answer 7

I'm not a huge fan of C either, since technically it is electrons flowing, not charge. Electrons have a charge, but electrons are what're flowing.

Answer 8

as to positive or negative charge flow is matter of convention

Answer 9

Well current is \[i = \frac{dq}{dt}\] Only charge fits in

Answer 10

But the most correct response is C

Answer 11

Yes I agree C is the one to choose

Answer 12

Oh that's right. Electrical charge flows the opposite direction that the electrons flow.

Answer 13

It doesn't matter which charge whether positive or negative so it is c

Answer 14

Also you can't really say that electrons are "moving" in the way we think of moving. You have probability clouds of possible positions for the electron assigned a probability. And I think when it jumps to another atom it doesn't "move" in the classic sense.

Answer 15

hm

Answer 16

no it moves with approximately 10^-4 m/s

Answer 17

I'm just saying that electrons aren't really little balls that move around in orbits.

Answer 18

but there are so many charges the potential dissipates at light speed as it is em wave and every charge particle start moving or I may say their random movement now becomes a lil oriented thats all with positive and negative in opposite directions it is same process compared to the semiconductors hole n all

Never Mind

Answer 19

Everything about subatomic particles is viewed statistically. Quantum mechanics and the uncertainty principle etc

Answer 20

wow such in depth answers.

Answer 21

yeah it is all i am saying is creation of negative and positive charge of course there is uncertainty

Answer 22

i haven't had quantum but i read a lil about uncertainty principle and all

Answer 23

Its "weird" in the sense that things don't behave at all like they do in classic Newtonian mechanics

Answer 24

yeah it is they have uncertainty with everything like electron orbits..Newtonian every thing is certain

Answer 25

yeah

Answer 26

Alchemista you must be in college you know so much about them
