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
In a circuit is current proportional to resistance?
Ohms law is: I = V / R (current = voltage / resistance)... where if the voltage or resistance changes then the current will change. ... the current and resistance is a inversely proportional linearly relationship ...this means that if the resistance doubles then the current halfs, if the resistance halfs then the current doubles, etc...hope this helps
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
When a current passes through a resistance what happens to the electric energy that is lost?
Becomes heat.
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.
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 a circuit if the resistance is increase?
If resistance is increased, current decreases. Ohm's Law: current equals 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 to current flow when the resistance is higher than normal?
For a specific voltage, current flow is inversely proportional to resistance.
What happens when current reaches a insulator?
The current will take the path of least resistance.
What happens when you halve the resistance in a circuit when voltage remain constant?
Since resistance is the ratio of voltage to current, we can say that halving the resistance will result in twice the current.
