If a circuit existed where a wire could be made smaller AS the current from a defined source was applied to a defined user then in terms of amperage there would be little change in that parameter. In terms of the Power dissipated as heat through the electrical resistance of the wire then the wire would exhibit a marked increase in the heat expended (Power -watts= amperage- I x voltage -E) . With this in mind and using the same formula as noted the increase in P can only be attributed to an increase in E .To maintain the amperage -I. In short the smaller the wire the greater the voltage must be to maintain a set unit of amperage. In real world projects however the user raises wire size and does not modify voltage to maintain the amperage capacity. This is covered by the idea of calculation of voltage drop in a conductor based on its cross sectional area. From your question let me remind you that amperage is a function of usage and although stated on many devices does not exist until a circuit is closed ..Have a good one Edesigner.

∙ 13y agoas with any electrical system if resistence is increases then current and voltage will be reduced.

and nothing else changes, the current through the component
decreases.

What happens to an electric current when the wire is made smaller?
Electric current as we usually describe it is the flow of electrons. Current is caused to flow by voltage, which can be looked at as "electrical pressure" that forces electrons to move. Currents can be made smaller or larger by decreasing the voltage across a fixed amount of resistance. As resistance is the quality of "resisting" or "limiting" current flow, we can change resistance to change current. For a give voltage, if we increase the resistance, we can make the current smaller, and if we decrease it, we can make current larger. In electronics, voltage equals current times resistance. E = I x R Also true is that current is equal to voltage divided by resistance. I = E/R As current equals volts divided by resistance, if we change one of them without changing the other, current will change. And in increase in voltage (with no change to resistance) will cause current to go up. The opposite is also true. Also, if we increase resistance (with no change in voltage), current will go down. And the opposite is true here, too.
What is added to a circuit to make the current smaller?
The reduction of voltage or the increase of resistance will reduce the current in a circuit.
When a resistor has another one connected in parallel with it is the combined resistor greaterthe same or smaller?
Think it through. You are adding a second path for current flow. Current flow will increase to some extent. Therefore, with more current flow, resistance must....
How can the current flowing in a electric circuit be increased?
we have to increase the winidin count of Coils inside the Alternator and also the Carbon mesh brush is to be increased so that the higher electric output will be produced................
Resistance increases what happens to amperage?
yesAnswerNo! Resistance is determined by the length, cross-sectional area, and resistivity of a conductor. Resistivity is, in turn, affected by temperature -so temperature indirectly affects resistance.These are the only factors that affect resistance. Voltage and current have no direct effect whatsoever on resistance. Current can affect resistance indirectly if it causes the conductor's temperature to increase.For AC circuits, 'skin effect', due to frequency, causes the current to flow towards the surface of a conductor which acts to reduce the effective cross-sectional area of that conductor. So, frequency can also indirectly affect resistance.

What happens to the electric current when the wire is made smaller?
If wire delivering a certain amount of current is made narrower, the resistance of the wire will increase. This will limit current, and the wire will warm up some. If the wire is made shorter, resistance will decrease. The electrical codes have well published limits on the amount of current different types of wire can carry.
What is the difference of voltage resistance and current as the apply to electric circuit?
E=IxR E- Electromotive Force, measured with voltage - volt - v. I- Current, measured with amperage - amp - a. R- Resistance measured with ohms - (Greek omega symbol) Voltage = pressure. Current = flow. Resistance = opposition to flow such as wire size or load. If electricity was water then the water pump is the voltage. The water flowing through the pipe is the current and the size of the pipe is the resistance. Smaller pipe more resistance.

An ammeter and voltage range are measure the current and voltage electric lamp if mistake meter interchange what will happen?
1. Voltmeter has high impedance and hence will restrict the current severely.a) Electric Bulb will not glowb) The Ammeter will just measure the current that Voltmeter allows and since this current is much smaller than actual current nothing will happen to ammeter.c) The Voltmeter will measure the Voltage that is being applied.d) This will allow you to measure the resistance of the Voltmeter.VR=V/I
Will current travel along the path with the highest resistance?
Current goes path of least resistance. But if u have two resistances in paralell only the majority will go through the smaller resistance some Porportional Amount will "flow" through the larger resistor. Depends on resistance sizes and voltage slap plied as to how much current

Why does the skin effect in radio frequency caused?
Skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor so that the current density near the surface of the conductor is greater than that at its core. That is, the electric current tends to flow at the "skin" of the conductor, at an average depth called the skin depth. The skin effect causes the effective resistance of the conductor to increase with the frequency of the current because much of the conductor does little. Skin effect is due to eddy currents set up by the AC current. At 60 Hz in copper, skin depth is about a centimetre. At high frequencies skin depth is much smaller.
What is an electric current made of?
It is made out of small particals, smaller than atoms called electrons.
