If all environmental conditions remain constant then the resistance will not change appreciably with applied voltage, but the current will increase. An increase in current will raise the temperature of the conductor which will increase the resistance somewhat.
If you increase the voltage applied to a conductor, the current increases.That is, unless you are talking about stepping up the voltage with a transformer with the intent of distributing it over a long distance to a remote transformer, at which point you would step it back down. In this case, the current would decrease. The above answer to the original question remains valid, however, due to lack of information.
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
The Ohm is a unit of measure of resistance to the flow of electricity. The ohm is defined as a resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere.
In a passive circuit, the current will decrease. In an active industrial circuit, it will usually decrease. In a theoretic manner - it is an unknown.
A wire with some resistance and a voltage applied to it The amount of current I passing this wire is V/R
No, the resistance is fixed by the cross section and length of the conductor and does not vary with voltage.
No, the resistance of a copper conductor does not vary according to applied voltage. It is constant for a given wire size, and only varies with temperature. Of course, current through a conductor causes it to heat, so current, not voltage, indirectlycauses a change in resistance.
Resistance is affected by the length, cross-sectional area, and resistivity of the conductor. The resistivity, in turn, is affected by temperature. So only by changing one of these four factors will the resistance of a conductor change. Changing voltage will have no affect upon the conductor's resistance.
Resistance is due to a property specific resistance of material. In no way resistance depends on the voltage applied. This is the case of ordinary conductor. But in case of semi conductor or insulator there may be chances to get a variation of conductance and hence resistance due to potential applied.

Electrical resistance is opposition to electric current flow. There is a resistance to the flow of current. And a "balance" between applied voltage and resistance determines how much current will flow in a circuit. For a given applied voltage, if we increase the resistance, the current flow will decrease. For that same applied voltage, if we decrease the resistance, the current flow will increase. It's a simple relationship, and it is set down by the following expression: E = I x R We can also write it as I = E / R and R = E / I Voltage (in volts) is E, current (in amps) is I, and resistance (in ohms) is R. In the first expression, voltage is equal to current times resistance. For a constant voltage, any increase in resistance will cause a decrease in current flow. And any decrease in resistance will cause in increase in current flow. Just as cited earlier.
Yes, your right.
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
he's a German physicist proposed ohm's law saying current in a conductor is proportional to the applied voltage divided by its resistance. such that resistance is constant.
That depends on the force applied.
The Ohm is a unit of measure of resistance to the flow of electricity. The ohm is defined as a resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere.
If force is applied in the line of motion, then motion will increase, but when it is applied opposite to the line of motion, then motion will decrease.
