Electron moving in a Copper Wire

[member 217843]

Homework Statement

How far does an average electron move along the wires of a 299 W toaster during an alternating current cycle? The power cord has copper wires of diameter 1.7 mm and is plugged into a standard 60 Hz 120 V ac outlet.

Homework Equations

P_rms=I_rmsV_rms
I_peak=I₀=I_rms(sqrt 2)
I₀=npAV_dmax
V_dmax=Aw=A(2pif)

The Attempt at a Solution

I figured out what equations I had to use, and I placed them above. I started to solve for I₀, but I do not know how to find n.

Hint -- google Copper Conduction Electrons, and you will find some pages that will answer the question about the number n for you...
