What happens to power dissipation of value of electric current passing through a conductor of constant resistance is doubled?
Power dissipation in a conductor is given by the formula ( P = I^2 R ), where ( P ) is power, ( I ) is the electric current, and ( R ) is the resistance. If the electric current is doubled, the new current becomes ( 2I ). Substituting this into the power formula results in ( P' = (2I)^2 R = 4I^2 R ), which shows that the power dissipation increases by a factor of four. Therefore, doubling the current through a constant resistance results in a fourfold increase in power dissipation.
What happens to current flow when the resistance is higher than normal?
For a specific voltage, current flow is inversely proportional to resistance.
What happens to an electric current when the wire is made smaller?
Electric current as we usually describe it is the flow of electrons. Current is caused to flow by voltage, which can be looked at as "electrical pressure" that forces electrons to move. Currents can be made smaller or larger by decreasing the voltage across a fixed amount of resistance. As resistance is the quality of "resisting" or "limiting" current flow, we can change resistance to change current. For a give voltage, if we increase the resistance, we can make the current smaller, and if we decrease it, we can make current larger. In electronics, voltage equals current times resistance. E = I x R Also true is that current is equal to voltage divided by resistance. I = E/R As current equals volts divided by resistance, if we change one of them without changing the other, current will change. And in increase in voltage (with no change to resistance) will cause current to go up. The opposite is also true. Also, if we increase resistance (with no change in voltage), current will go down. And the opposite is true here, too.
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
What happens if you turn off the electric current in the solenoid?
If you turn off the electric current in the solenoid, the solenoid quits pulling its armature.
What happens with electric current when applying the same voltage the resistance of the circuit is reduced?
As the resistance is reduced across the same voltage, the current increases.
What happens to the power of an electric circuit of the resistance is decreased?
if the resistance is decreased and the current stays the same, then the power decreases.
When a wire is made smaller the resistance increases. what happens to electric current?
increase
What happens to the electric current in a wire as voltage is increased?
As voltage is increased, the electric current in a wire also increases because the relationship between voltage, current, and resistance is described by Ohm's Law (V = IR). If resistance remains constant, a higher voltage will result in a higher current flowing through the wire.
What happens to the electric current in a wire when voltage is increaced?
If the load resistance is constant, then increasing the voltage will increase the current by the same proportion -i.e. doubling the voltage will double the current.
What happens to a wire when and electric current passes through it?
When an electric current passes through a wire, the wire heats up due to the resistance in the material. The current causes electrons to flow through the wire, creating a magnetic field around it. This effect is used in electromagnets and electric motors.
What happens to the current in a circuit if the resistance is increase?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
When resistance is in a circuit what happens to the current?
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
What happens to the current in the circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
What happens to the current as the resistance decreases?
it increases

What happens if the current pass through foil?
If an electric current passes through a foil, the foil will heat up due to resistance in the material. The degree of heating will depend on the amount of current flowing through the foil and the resistance of the material. Excessive current through a foil can lead to overheating and potential damage to the foil.
