Question
A wire with a cross-sectional area of 3.30x10^-6 m^2 has an electron density of 8.30x10^28 e-/m^3. If those electrons are displaced 4.5x10^-4 m in 1.00
A wire with a cross-sectional area of 3.30x10^-6 m^2 has an electron density of 8.30x10^28 e-/m^3. If those electrons are displaced 4.5x10^-4 m in 1.00 seconds, (a) how much current is running through this wire? This same wire has a resistivity of 1.72x10^-8, if the current traverses a length of 20.0 m along this wire, (b)what is the resistance the current encounters? (c) what is the potential drop across the 20.0 m of wire?
