A)1.25 V
B)0.80 V
C)20.0 V
D)3.20 V
E)zero

Question

Quizplus · Accepted Answer

The potential difference across the wire can be calculated using the formula:

V = E * L

where E is the electric field and L is the length of the wire.

Substituting the given values, we get:

V = 4.0 V/m * 5.0 m

V = 20.0 V

Therefore, the potential difference across the wire is 20.0 V. The correct answer is choice C.

A Wire of Length L = 5
