A Nichrome wire 25 cm long and 0.22 mm in diameter is connected to a 2.3 V flashlight battery.
(A) What is the electric field inside the wire?
(B) Why don't you have to know how the wire is bent? (Select all that apply.)
a. E is dependent on the length L of the wire which only applies to the segment of the wire that is not bent.
b. E is not dependent on how the wire is bent, only the diameter of the wire is needed.
c. Since the conventional current flows in the direction of E → , E is the same in every part of the wire with uniform properties.
d. E must be parallel to the wire at every location – even if the wire twists and turns.
