The current in the circuit is increased by increasing the voltage of the wire.
Further Explanation:
Ohm’s law
It is an important relationship between current, voltage and resistance. Ohms law states that the current through any conducting wire is directly proportional to the voltage across the wire and is inversely proportional to the resistance of the wire.
The mathematical expression for the relation is as follows:
[tex]{\text{V}} = {\text{IR}}[/tex]
Where,
V is the voltage applied measured in volts.
I is the current flow in the wire measured in ampere.
R is the resistance posed measured in ohm.
There are various factors that affect the resistance in a wire, which in turn affect current, that is, length of the wire, area of cross section and nature of the wire.Resistance is directly proportional to the length of the wire and inversely proportional to the area of cross section of the wire. Therefore if the length of the wire increases, the resistance of the wire too increases, which decreases the current flow from the wire. Similarly current has a direct relation to the area of cross section of the wire.
If resistance is kept constant, then the current in the wire can be increased by increasing the voltage of the wire.
