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.
What else can I help you with?
Will the resistance of a copper conductor decrease with an increase in the applied voltage?
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.
Will an increase of applied voltage decrease the resistance of a copper conductor?
No, the resistance is fixed by the cross section and length of the conductor and does not vary with voltage.
The resistance of a copper conductor will decrease with an increase of applied 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.
What are two ways to increase the current in a wire?
Increase the voltage applied to the wire. Decrease the resistance of the wire.
Does increasing potential difference increase 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.
What does Ohm's law describe about the relationship between voltage, current, and resistance?
Ohm's law describes the relationship between voltage, current, and resistance in an electrical circuit. It states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. This means that if the voltage increases, the current will also increase, but if the resistance increases, the current will decrease.
How does the drift velocity of electrons in metallic conductor change if the length of the conductor is doubled by streching keeping the applied p.d.constant?
If the length of the conductor is doubled while keeping the applied potential difference constant, the drift velocity of electrons will decrease by half. This is because a longer conductor provides more resistance to the flow of electrons, leading to a decrease in the overall drift velocity.
What cause acceleration to decrease?
Acceleration can decrease due to friction, air resistance, or an opposing force acting in the opposite direction to the motion. An increase in mass or a decrease in the force applied can also cause acceleration to decrease.
How can the current in a conductor be increased?
The current in a conductor can be increased by either increasing the voltage applied across the conductor or decreasing the resistance of the conductor.
When a larger voltage is applied to a conductor does the current increase or decrease?
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.
How does electrical resistance change the current in a circuit?
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.
If power is constant increasing the voltage will increase or decrease current?
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.
