Voltage difference and distance between wires

In summary: The potential difference will remain the same.In summary, a question was asked about the potential difference between two points in a circuit when the distance between them is changed. However, without knowing the specifics of the circuit setup, it is difficult to provide a definitive answer. If ideal wires with zero resistance are used, then the potential difference will remain the same regardless of the distance between the wires.

Hi, Everyone,

Just a quick question. In the diagram on this link, is V2 < V1 ?

Thanks.

Welcome to PF, ZPlayer.

Your diagram is meaningless, because it contains no information about what the lines mean. If you post a homework question here:

1) You must post the entire question, exactly as it was given to you.
2) You must post in the correct forum (not this one).
3) You must show your work and explain where you are stuck. Only then will you receive help.

Basically my question is the following. Suppose the positive and negative poles of DC source are connected to wires. If the distance between wires increases, will the potential difference between the wires decrease?

Does the circuit setup consist only of wires? Are these wires treated as ideal wires, with zero resistance? Do you want to take inductance into account? I don't know the assumptions you're making in the circuit setup, so clearly the answer to your question will depend on what you assume.

Yeah, basically I was thinking about ideal wires (R == 0.) The question is whether potential difference between any two given points on the circuit will change in case if these points are moved further (or closer) apart without disrupting the configuration of the circuit.

If you're using ideal wires, then clearly the distance in between the wires doesn't change anything.
 

What is voltage difference?

Voltage difference, also known as potential difference, is the difference in electric potential between two points in an electric circuit. It is measured in volts (V) and is a measure of the energy required to move a unit of charge between the two points.

How is voltage difference related to distance between wires?

The voltage difference between two wires is directly proportional to the distance between them. This means that as the distance between the wires increases, the voltage difference also increases. This relationship is known as the inverse square law, where the voltage difference is inversely proportional to the square of the distance between the wires.

Why is voltage difference important?

Voltage difference is important because it is the driving force behind the flow of electric current in a circuit. It is responsible for the movement of electrons from a high potential (positive) to a low potential (negative) in order to equalize the potential difference between the two points.

How does voltage difference affect the strength of an electric field?

The strength of an electric field is directly proportional to the voltage difference between two points. This means that as the voltage difference increases, the electric field strength also increases. This is why high voltage power lines have stronger electric fields compared to low voltage power lines.

What happens if there is a large voltage difference between two wires?

If there is a large voltage difference between two wires, it can lead to a phenomenon called arcing. This is when electricity jumps across the gap between the wires, causing sparks and potentially damaging equipment. It is important to maintain appropriate voltage levels and distances between wires to prevent arcing and ensure safe operation of electrical systems.
