Question

What is the potential difference between two points seperated by a distance 'l' in a conducting wire?​

Answer 1

Answer:

the potential energy b/w 2points ∆V is often called voltage

Explanation:

it is given by ∆V=VB-VA=∆PEq.the potential distance at an infinity is often zero.

Answer 2

To find:

The potential difference between two points seperated by a distance 'l' in a conducting wire?

Calculation:

2 cases are possible:

• If wire is ideal and doesn't have any resistance.

• If wire itself has resistance.

In case of ideal wires:

• The ends of the wire will have same voltage.

• Hence ∆V (potential difference) across the ends of the wire will be zero.

In case of non-ideal wires:

• The ends of the wire will not have potential.

• ∆V = V_(A) - V_(B) , A and B are the ends and A is higher potential than B.

• So, there will be Potential GRADIENT in the wire.

• Potential Gradient = ∆V/l
