Question

Which of the following correctly describes the result of a voltage difference
A.Charges move randomly
B.Charges not to move
C.Charges flow from low voltage areas to high voltage areas
D.Charges flows from high voltage areas to low voltage areas

Answer 1

Voltage is the potential to make charged particles move:

Answer 2

the correct option is c and d and it depends on charge wether it is positive or negative that it will flow from high potential to low potential or low ti high

Answer 3

anshu25 gives a good answer.

Answer 4

C and D both seem correct. But D seems the best fit.

Answer 5

Yes, charges move from high potential to low potential, just like in biology, diffusion occurs from a high membrane potential to a area of low potential

Answer 6

First, note that the amount of charge passing a point in a given time is called current and is measured in Amperes where \[1A=1\frac{Coulomb}{second}\].
The flow of charge (current flow) can be taught one of two ways:

Conventional flow or "hole flow" - This is where current flow is taught to be from + to - and was the original way they thought it worked when electricity was first discovered. The nickname "hole flow" comes from the thought that as electrons move to more positive areas in a conductor, they leave holes behind that move to more negative areas.

Electron flow - This is how electrical current actually flows since the electrons are the charge carriers in conductors.

The method you choose to use in physics/electronics classes/etc doesn't really matter in most circumstances since it's just a convention. As with any convention, you just have to make sure you stick with it throughout a problem.

All that being said, D is almost certainly the answer since most physics courses teach conventional current flow these days...at least as far as I've seen. If you ever get into electronics, electron flow becomes the method that is typically taught.

BTW: Some textbooks even have 2 versions...one for each convention depending on which one your school chooses to teach.

Answer 7

thank you all it helped d was correct
