Electric Fields in Conductors Video Lessons

Concept

# Problem: The electric field inside a 30-cm-long copper wire is 0.010 V/m.What is the potential difference between the ends of the wire?

###### FREE Expert Solution

The potential across the ends of the wire can be expressed as:

$\overline{){\mathbf{∆}}{\mathbf{V}}{\mathbf{=}}{\mathbf{E}}{\mathbf{L}}}$, where L is the length of the inductor and E is the electric field within the conductor.
