When a wire is amde smaller the resistance increase what happen to the electric current?
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.

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?

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.
Unit of electric resistance?
The unit of electric resistance is the ohm, represented by the symbol Ω. It measures the opposition that a material has to the flow of electric current through it. Smaller resistances allow for a larger current flow, while larger resistances restrict the current flow.
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.

Why a smaller diameter wire has more resistance of electric current?
Resistance is defined as a property of materials due to which a material opposes the flow of current through themselves. And Resistance is inversely proportional to area of cross section of conductor. As the cross section area of thin wire is less hence resistance is more. So, as wire diameter increases its resistance decreases and vice versa
What happens to resistant if wire diameter is decreased?
If the wire diameter is decreased, the resistance of the wire will increase. This is because with a smaller diameter, there is less cross-sectional area for the electrical current to flow through, causing more hindrance and resulting in higher resistance.
Would vasoconstriction decrease peripheral resistance?
No, vasoconstriction would increase peripheral resistance. When blood vessels constrict, the diameter of the blood vessels becomes smaller, which increases resistance to blood flow. This can lead to an increase in blood pressure.
