O 2/3 points | Previous Answers MI4 18.10.037 Nichrome wire 28 cm long and 0.26 mm in diameter is connected to a 3.4 V flashlight battery. What is the electric field insid 12.14 V/m Why don't you have to know how the wire is bent? (Select all that apply.) a E is not dependent on how the wire is bent, only the diameter of the wire is needed. must be parallel to the wire at every location-even if the wire twists and turns. E is dependent on the length L of the wire which only applies to the segment of the wire that is not bent. Since conventional current flows in the direction of E, E is the same in every part of the wire with uniform properties

Explanation / Answer

Given that,

L = 28 cm = 0.28 m

d = 0.26 mm

V = 3.4 V

Electric field inside the wire,

E = V / L

E = 3.4 / 0.28

E = 12.14 V/m

You don't have to know how the wire is bent because,

- E must be parallel at every location even if wire is bent and twist.

- Since conventional current flows in direction of E, E is same in every part of wire with uniform properties.
