Yo! Anyone know of any free font compatible with Word (or that comes with Word!) that has the goddam electric field symbol in it? Whoever came up with that sign had an irrational hatred of word processors.
No, it's not in the Greek alphabet. If it were, that would be cool since loads of standard fonts have Greek characters.Crosson said:Do you mean epsilon? It's a greek letter.
[tex] \epsilon [/tex]
In American textbooks I often see E as the electric field and epsilon as the energy density.

Daniel.
Tom Mattson said:Or how about [itex]\cal E[/itex]?
It looks a lot like xi, and I've been using that, but I don't think it is, since the textbook has used the xi symbol too and they're clearly different.
Is that upper-case epsilon? Dammit, guess what upper-case epsilon is in Word... 'E'! Well, at least that explains the interchangeability of electric field symbols... blame the greeks I guess.whozum said::tongue: dex :tongue:
Thats the one Tom Mattson pasted, except more elaborate (I believe).
The electric field symbol represents the strength and direction of the electric field at a particular point in space. It is used to describe the force that a charged particle would experience at that point.
The electric field symbol is typically represented by the letter 'E' with an arrow pointing in the direction of the field. The length of the arrow represents the strength of the field.
The units of the electric field symbol are newtons per coulomb (N/C) in the SI system. In other systems of measurement, it may be represented as volts per meter (V/m).
The electric field symbol is related to electric potential through the equation E = -∇V, where E represents the electric field, V represents the electric potential, and ∇ represents the gradient operator. This means that the electric field is the negative of the gradient of the electric potential.
Yes, the electric field symbol can be negative. This indicates that the field is directed in the opposite direction of the arrow, and the force on a charged particle would be in the opposite direction. A negative electric field can also indicate that the field is decreasing in strength as the distance from the source increases.
