Ohm's law. Current is directly proportional to the applied emf and inversely proportional to the resistance in the circuit.

You can increase the current in a wire by increasing the voltage applied across it, reducing the resistance in the wire, or increasing the number of electrons flowing through the wire per unit time.

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 actions will not increase the electric current induced in a wire?

Actions that will not increase the electric current induced in a wire include changing the wire's length or material, adjusting the wire's temperature, or altering the wire's tension. Inducing a current involves changing the magnetic field around the wire, so actions that do not affect this magnetic field will not increase the induced current.


What are two ways increase the current in the wire?

You can increase the current in a wire by increasing the voltage applied across it or by decreasing its resistance. Additionally, increasing the cross-sectional area of the wire can also help facilitate higher current flow.


How do you change the current in a wire?

To change the current in a wire, you can adjust the voltage applied to the wire or change the resistance in the circuit. Increasing the voltage will increase the current as per Ohm's Law (I = V/R), while decreasing the resistance will also result in an increase in current.


What happens to the current carrying ability of a wire when the temperature increases?

What are some ways to increase the magnetic field around a wire?

There's only one way to do that: Increase the current (amperes) in the wire.


What happens if you increase the current in a wire?

Increasing the current in a wire will lead to an increase in the heat generated in the wire due to the higher power dissipation (P = IΒ²R). This can cause the wire to heat up, potentially leading to overheating and damage if the current is too high for the wire to handle. Additionally, increasing the current can affect the magnetic field generated around the wire, influencing nearby components or devices.

When you loop the wire with a current it will?

increase the strenght of the magnetic field. :)


If You wrap a wire around a piece of iron. If you slowly increase the strength of an electric current flowing through the wire you would expect .?

The temperature of the wire will increase and eventually like the "straw breaking the camel's back" the wire will fail if you apply enough current. It is like exceeding the current in a fuse, the wire essentially disintegrates.


What happens to the magnetic field if the current in the wire increases?

If the current in the wire increases, the magnetic field also increases.
