How does the potential difference across the electric circuit affect current?

In a very simple way. As long as nothing changes in the circuit, the current that
flows from the power supply or battery into the circuit is directly proportional to
the voltage of the supply.
-- If you double the voltage across the ends of the circuit, the current will double.
-- If you turn the voltage up to 3.4027 times its original value, the current will increase
to 3.4027 times its original value.
-- If you decrease the voltage by 81.7 percent, the current will decrease by 81.7 percent.

Is the potential difference across an electric circuit with no element drawing current from it the same at every pt?
there should not be any diff.because
What do you nned to make an electric current?
An electrical potential difference (aka. a difference in applied voltage), and a conductor / circuit. Electrons would help too.
How can you measure electric potential and electric current?
Potential . . .Always measured as a potential difference between two points.The most practical way to do that is with a voltemeter connectedin parallel with any circuit between the two points.Electric current . . .The most practical way to measure current is with an ammeter connectedin series in the path of the current.
In an electric circuit resistance is?
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
What is th potential difference that causes charges to move in a circuit?
The answer is voltage, resistance, electric discharge, and current. It is caused by a difference in energy stability between two points that favors a charge to move down a potential difference.
How current electricity moves in a circuit?
You need a source of electrical potential difference, also known as voltage (which is the technical term for what for you call "electric pressure"). The easiest and most common voltage source is a household battery. Hook up the positive electrode of the battery using a conductor (eg. a copper wire) to one end of your circuit and the negative electrode to the other end, and voila, you'll have electric current flowing through your circuit.
What causes an elecrtic current to flow in a circuit?
The movement of electron towards the high potential causes electric current to flow in a circuit.
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
How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
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 causes potential difference?
A potential difference causes an electric current. Think of it like a river : the source of water is the most elevated point of the river, so the water has a lot of gravitational potential energy. The end of the river is the lowest point of it, so the water has very low gravitational potential energy. What happens between these two points? Water flows! This analogy can be applied to electricity; the potential difference is caused, for example, by a battery in an electric circuit.
