Of course there is. Those are related, but different aspects.

Think of voltage as being pressure in a water pipe.

Current if the flow of water in the pipe.

You can have pressure without flow, as when a valve is closed. But you cannot really have a flow without some pressure (I will neglet superconduction which is a special case in this analogy)

V = I x R

V = voltage
I = current
R = resistance
x = times (eg 2 x 4 = 8)

it can kind of be thought of as a vague metaphor for the flow of water.
I = current = the volume of water flowing in a river, hence the term current. The number of water molecules or the number of electrons which pass by a particular point or through a particular section of river.
R = resistance = any logs or dams or obstructions to the flow of water.
V = voltage = the speed that the water is flowing throught the river bed, where the river bed is vaguely similar to the wire that the electrons flow through.
Sorry this is not a good answer, don't keep it for more than a couple of seconds as a basic way to get yourself a less airy fairy undrestanding. There are many many holes in this metaphor, and in a literal sense it does not work effectively, but if you only need a little bit of an understanding of why voltage is different to current then this should give you the concept of how they are different.

Ya there is

Voltage is an electric potential difference between two points on a conducting wire. Voltage is measured in volts. Voltage comes from various sources. Two examples of these sources are batteries and electrical outlets.


whereas

Current is measured in amps. Current is charged particles which flow from the voltage source through conductive material to a ground.

They are related to each other by Ohm's law V=IR

a million. Voltage is the flair distinction between 2 factors of the circuit. a million. contemporary is the flow of electron interior the path of the cct. 2. The Unit of Voltage is Volt. 2. The Unit of contemporary is Amp. 3. 2 kinds of voltage. Dc voltage and ac Voltage 3. There are no longer any kinds of contemporary.

They are entirely different things. It might help if you imagined that an electrical circuit was like rolling a ball down a slope. The steepness of the slope can be considered similar to the voltage, and the weight of the ball is similarly like the current.

Voltage is pressure and current is flow.

If you think of electricity as water then you can see the concept.

The voltage in effect causes the flow according to the resistance of the circuit.

Ohms law states V=IxR

I = Amps (current)
R= resistance
V= Voltage

Yes. Voltage is energy per charge. A voltage of one volt means that each coulomb (6*10^18 electrons) looses or gains one joule of energy by traveling from one pole to the other.

Current is charge per time. One ampere means that each second one coulomb leaves or arrives.

Another answerer wrote that you could think of voltage as the steepness of a slope, but that's not entirely accurate. Voltage is like the difference in height of the two endpoints. The steepness of the slope is analogous to the electric field strength, which is measured in volts per meter, or newtons per coulomb.

Voltage is electromotive force which makes the electrons move, which is current. Current is rate of movement in an electrical/electronics circuit, measured in amps, or smaller units .

Volts are also know as Potential Different, ie a measure of the push to get round a circuit

Volts give the jolt
Ampage the damage

2006-08-23 01:28:38 · answer #9 · answered by paul B 3 · 1 1

I would think so, seeing as a potential difference (IE voltage) is what causes the flow of charge (IE current)
