what is voltage?

Question

A) the potential energy to move charged particle
B) the movement of charged particle
C) the potential energy to move any particle
D) movement of any charged particles

Answer 1

A) The potential energy to move charged particle.

Think of it as pressure.

Answer 2

first of all the voltage is an Energy .

if U is a potential energy of a system , then the potential energy per unit charge is U/q and has a unique value at every point in an electric field. this quantity U/q is called "electric potential" (or simply the potential V . Electric potential at an arbitrary point in an electric field equals the work required per unit charge to bring a positive test charge from infinity to that point

so at that point , in reality , V represent the potential difference between the point chosen and a point at infinity . Because electrical potential is a measure of potential energy per unit charge, the SI unit of both electrical potential and potential difference is Joules per coulomb, which is defined as a "volt"

1volt=1joule/1coulomb

That a 1J of work must be done to move a 1C charge through a potential difference of 1V

Now from the above definitions V=U/q
U is an energy >> then V is an energy too
if the particle that we move is not charged then q=0 so , V is undefined .. so the particle have to has a charge q

Finlay the answer will be
A) the potential energy to move charged particle

I hope i could help you :) . plz contact me if you have any questions ..

Answer 3

"A" is correct. Voltage IS a potential energy, much like water pressure behind a garden hose valve. The pressure, and therefore the capacity to preform work, is there, whether "the valve" is open or not. And it does tend to move charged particles, though in most cases, a voltage source actually imparts a charge to normally uncharged atoms, sucking electrons right out of their outer shells.

"B" is not correct - many things other than voltage can cause a charged particle to move, and you can have voltage yet not have any movement of charged particles.

"C" - Nope. Sounds more like "gravity" to me...

& "D" - Nope. That would be "current", the actual flow in electrons per second past a given point, and similiar to the water in the pipe.

To reiterate, voltage is like the pressure in a water pipe, whether there is any actual water flow or not. Current is the water.
