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.)

Respuesta :

Answer:

7.05 Volts/m

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

[tex]E = \frac{V}{L}[/tex]

Inserting the values

[tex]E = \frac{3.1}{0.44}[/tex]

E = 7.05 Volts/m
