When does current stop flowing in a circuit?
Current flows in a circuit when there is a difference in electronic potential between two points.
Does potential difference change with change in resistance?
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
What happens in a circuit to voltage when current flows?
A: There is a relationship one needs the other both can coexists but not each alone.
How is electrical current produced?
A potential difference (volts) is set up between the two ends of a conductor. If there are any electrons available to move, then their negative electric charges persuade them to move away from the more negative potential and toward the more positive potential, resulting in current.
What is produced first current or voltage?
current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.
What type of current has steady potential difference across a circuit?
That would be DC or Direct Current.
When does current stop flowing in a circuit?
Current flows in a circuit when there is a difference in electronic potential between two points.
What happens to current in a simple circuit as potential difference is increased?
depends on the simple circuit. please describe it.
Does potential difference change with change in resistance?
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
What conditions are necessary for a current to be present in a circuit?
some resistance and potential difference
How does voltage produce current?
Voltage across two terminals mean there exists a potential difference, and when the circuit gets closed, due to this potential difference the current flow.
If there are 2 points with different potential energy will there still be an electrical current through the circuit?
Not necessarily. The two points with potential difference, will have to be connected via a conductor, for current to flow.Provided that a circuit exists, then current WILL flow.
What is basic difference between Potential meter and rheostate?
Potential meter is voltage control device and rheostate is current control device. it is a basic difference.
Is a car battery a circuit?
Hi, there. A battery is a power supply, a source of potential difference which drives current. In itself, a battery is not a circuit, but if you attach it to a load (a resistance), then a current will form and a circuit is made!
What happens in a circuit to voltage when current flows?
A: There is a relationship one needs the other both can coexists but not each alone.
8 If the resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V the current flowing through the circuit is?
There is a simple equation relating voltage (properly potential difference), current and resistance: V=IR Where V=potential difference, I=current and R=resistance So to answer: I=60/12 I=5
When the potential is high the current passing through a conductor it is also high true or false?
I think you mean when the 'potential difference' is high, is the current also high? The answer is that it depends on the impedance (a.c.) or resistance (d.c.) of the circuit. If this remains constant, then raising the potential difference will cause the current to increase too.
