Question

A Nichrome wire 44 cm long and 0.30 mm in diameter is connected to a 3.1 V flashlight battery. What is the electric field inside the wire? (Enter the magnitude.)

Answer 1

7.05 Volts/m

Step-by-step explanation:

L = length of the Nichrome wire = 44 cm = 0.44 m

V = Potential difference across the end of the wire = battery voltage = 3.1 Volts

E = magnitude of electric field inside the wire

Magnitude of electric field inside the wire is given as

`E = (V)/(L)`

Inserting the values

`E = (3.1)/(0.44)`

E = 7.05 Volts/m
