We generally think of electric current as a scalar quantity. When we think of 1/4th amp or 20 amps, we think of an amount (a scalar quantity) of current flow. On another plane, the electromagnetic forces at work in current generation are actually force vectors. In the traditional sense, electric current, which is the movement of electrons, is from negative to positive. This is not a vector, though. In the macro or "large" world, think of current as scalar.
---------------------------------------------------------------------
The beauty is that though current is not a vector definitely its direction of flow is used to make length as vector. I is not vector. dl is not vector but I dl will be considered as vector. So innovative and essential concept.

Current density is a vector which appears in Maxwell's equations.

A current is defined by size and direction amongst other things. Electric motors and dynamos, anything that depends on changing magnitude and direction of electric currents, rely on both of these properties. So if it is not a vector, in many circumstances it behaves as though it is. Light depends on displacement currents which are defined in terms of size and direction.

What is electric potential dependent upon?
The magnitude of the electric potential is dependent upon the particle's charge and the electric field strength.
Is Electric displacement density scalar quantity?
no, it's a vector dude
Does an object with twice the electric potential of another have twice the electrical potential energy?
Yes. Electric Potential energy E= VQ thus 2VQ = 2E.
What is used to measure potential difference?
A Volt meter is used to measure potential difference (a.k.a. voltage). Potential difference is measured in units called: Volts (V).
What is voltage what is another name for votage?
What is voltage what is another name for voltage? That is potential difference. In physics, the potential difference or p.d. between two points is the amount of work that would need to be done on a unit electric charge to move it from one point to the other against an electric field. P.d. is synonymous with voltage and is measured in volts. http://en.wikipedia.org/wiki/Potential_difference http://en.wikipedia.org/wiki/Voltage Cheers ebs
Is a electric potential scalar or vector?
Electric potential is a scalar.
What is the technical description of an Electromagnetic four-potential?
An electromagnetic four-potential is a relativistic vector function from which the electromagnetic field can be derived. It combines both an electric scalar potential and a magnetic vector potential into a single four-vector.
What is the difference between electrical potential energy and potential difference?
Electric potential is the electric potential energy per unit coulomb. So unit for electric potential is J/C and that of electric potential energy is simply J
Electric potenial scalar or vector why?
Electric potential is a scalar quantity since work done and charge are scalars
Is electric potential energy a vector or scalar quantity?
Electrical Potential Energy is a scalar or real number. Ep = zc e2 /4pi r.Total Energy is a Quaternion, the sum of the real or potential energy and the vector energy, Ev= mcV;E = Es + Ev = zc e2 /4pi r + mcV where Ev = mcV and V is the vector velocity.
The volt is the unit of electric?
Yes, the volt is the unit of electric potential or electromotive force. It represents the amount of potential energy per unit charge.
What difference between electric potential energy and mechanical potential energy?

Is an electric field a potential field?
no electric field is not a potential field .ELECTRIC FIELD IS A SCALAR QUANTITY WHERE AS POTENTIAL IS THE VECTOR QUANTITY. NO SCALAR QUANTITY HAS A FIELD SO THERE IS NO RELATION BETWEEN ELECTRIC FIELD AND POTENTIAL OR IN OTHER WORD POTENTIAL HAS NO FIELD <<>> An electric field is a vector field, because it has magnitude and direction. A pair of charged parallel plates has an electric field between them directed from the negative to the positive plate. The electric field is the gradient of the potential, which is another field but a scalar one. A field is just a quantity with a value that depends on positon. The potential is measured in volts and if one plate is grounded and the other at positive potential V, the potential rises from zero to V as the position changes from the lower plate to the top one.
What are the various potentials used in antenna theory?
scaler electric potential vector magnetic potentials retarded potentials
What kind of difference is measured in volts?
Volts are a measure of electric potential difference.
Poem about electric potential and potential difference?
Electricity will rule the world one day.
What is the difference between electrical potential and electromotive force?
electric potential is potential difference between two points in closed circuit. but electromotive force is potential difference in any open circuit.
