Physics: W=VQ - what does that mean?!?

Question

In simple language please - i'm not too hot at Physics.

Answer 1

W = work or energy

V = voltage difference

Q = charge



The equation says that the work done by an electric field is the change in voltage times the charge.

Answer 2

In an electrostatic field.

Let V volts is the potential at a point and you want to place a charge Q coulombs at that point by bringing it from infinity or from some other point where you assume potential is zero Volts.



Then by definition, V is the work done per unit charge.



Total work done = W = VQ in Joules

Answer 3

It means that if u take a charged particle from point A to point B, along any path, then the work done (W) is equal to the potential difference (V) multiplied by the charge of the particle (Q).



W = VQ



The potential difference mentioned is that set up due to other charges. Not due to the charge u are carrying.



U must use the proper signs in the formula. thus a negatively charged particle has a charge of - 1 C or - 2 C or whatever and a positively charged particle has a positive charge.



Also V = final potential - initial potential

Answer 4

Work equals electric potential times charge. The equation gives the amount of work in Joules that must be done (energy expended) to move a particle of charge q Coulombs through a potential difference of V volts.

Answer 5

W is a non-standard abbreviation for work which is another way of saying energy.



You may have learned



E = q * V



You have a charge q (coulomb) and a voltage V (volt). The work done to move the charge to this point aginsth the repulsive force is E (joule)

Answer 6

Vq W

Answer 7

I am not familiar with that. Where did you get it? They have to tell you what W, V, and Q stand for.
