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.
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.
Can you list three ways you can change the current in a circuit?
Increase, decrease, or remove the load <<>> Change the voltage and the current will also change in direct proportion, Ohms law.
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.
If you decrease resistance the current will increase or decrease?
It depends on whether the material is ohmic or non-ohmic.If it is ohmic, then it will obey Ohm's Law, and its resistance will remain constant if the current decreases.If, on the other hand, it is non-ohmic, it will not obey Ohm's Law and, if the temperature of the conductor falls (assuming it is a metallic conductor) due to the fall in current, then its resistance will fall too.
Does transformer doubles the power?
No. Power is constant. Transformers neither increase nor decrease power, except for minor losses. They increase or decrease voltage, and they decrease or increase current, but the product of voltage and current, i.e. power, remains the same.
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.
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.
What is applied to a conductor to cause current flow?
voltage is applied to a conductor to cause a current flow
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.
Does the magnetic field increase or decrease if the current is decreased?
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism 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.
Can you list three ways you can change the current in a circuit?
Increase, decrease, or remove the load <<>> Change the voltage and the current will also change in direct proportion, Ohms law.
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.
When does current flow through a conductor?
When a voltage is applied across it.
Does a change in current assets increase or decrease cash flow?
It depends on the current asset, so the change of current asset might be increase or decrease cash flows.
What happens to the electrons in a conductor when there is a potential difference between the conductor's ends?
The free electrons in a conductor will, when a difference of potential (voltage) is applied at its ends, participate in electron current flow (or just current, if you prefer). The voltage applied to the conductor will drive current through the conductor, and the free electrons will support current flow. These electrons will actually move through the conductor. As electrons are driven into one end of the conductor, the free electrons "shift over" and electrons stream out the other end of the conductor. This is the essence of current flow in conductors.
