Force that keeps current flowing?

Answer 1

voltage/electromotive force

Answer 2

The electric and magnetic forces act on charges to make them move around (current flow).

These forces are the source of voltage or electromotive force (which is somewhat misnamed, since it isn't really a force).

Conductivity plays a role by making it easy for the charges to get around, but it isn't the driving force

Answer 3

Voltage refers to the force that drives current. Amperage refers to the amount of current flowing. Resistance refers to the impedance to flow. They are related by the equation:

V = I x R (voltage = current x resistance)

Answer 4

i see it as the diffusion of electrons from high to low concentration.. just as a gas would diffuse to equally fill its environment or salts diffuse through water. the high concentration of electrons in a battery therefore keep the diffusion occuring as the concentration gradient decreases as we get further away from the batteries anode (its -ve side).

the electrons try and get to the cathode..the positive side of the battery, because essentially it lacks electrons and they diffuse there..however as the electrons diffuse to the cathode they balance out the concentration and stabilise the chemicals inside the battery, so they stop flowing. recharging the battery involves running this process in reverse basically.

Voltage is like the amount of energy each electron has (measured in joules per coulomb..a coulomb is a large number of electrons..eg 1 volt is 1 joule of energy in every coulomb of electrons)..

current is the number of coulombs passing through a given point in a second..so essentially the number of electrons passing through the material..the greater the current, the more electrons are flowing through.

Answer 5

That's a lot more complicated that you think actually. Yes, it's voltage, but there are technically other factors at play, but they are probably not of interest.

Answer 6

electro motive force

Answer 7

conductivity

Answer 8

the wind.....
