Volt Flashlight
A nichrome wire 95 cm long and 0.25 mm in diameter is connected to a 1.5 volt flashlight battery. ?
A nichrome wire 95 cm long and 0.25 mm in diameter is connected to a 1.5 volt flashlight battery.
a) What is the electric field inside the wire?
b) What is mobility, if the drift speed is 0.01 mm/s?
c) The Nichrome wire is replaced by a wire of the same length, and material, but a diameter, which is 5 times smaller. What is the electric field inside the new wire?
Please help me with this..
Thanks!
I would think that the answer to a) and c) is 1.5 v / 0.95 m = 1.58 v/m
I have no idea about b).
