A 10.0 cm length of copper wire has a uniform cross-sectional area of 1.0 mm2. If the drift speed of electrons in the wire is: 2.0x10-4 m/s and the electrons all move directly along the wire, what is the magnitude of the current density? What is the total current carried by the wire.
What current in a copper wire with a cross-sectional area of 7.08 x 10 m2 would result in a drift speed equal to 4.51 x 10-4 m/s? Need Help? Talk to a Tutor
9.0×1015 electrons flow through a cross section of silver wire in 380 μs with a drift speed of 7.8×10−4 m/s . What is the diameter of the wire? Express your answer to two significant figures and include the appropriate units.
An aluminum wire has a mobile charge density is 8.0e28 electrons/m3, and a cross-sectional area of 2.3e-6 m2. When a current flows through the wire, the average drift speed of the electrons is 1.7e-4 m/s. What is the current in the wire?
What is the resistance per meter of an gold wire with a cross-sectional area of 2.4×10−7 m2 . I used ----- (Resistance)/(cross sectional area) and (2.44* 10^-8) / (2.4 *10^-7 ) but it is wrong... Thank you for the help in advance!
A gold wire (cross sectional radius is 1.15x10-4m) is connected to a battery and attached to a 85.0Ω load resistor, as shown. The battery output voltage (Vo) is 9.0V. i. Determine the charge carrier density for the gold wire. Assume gold has one charge carrier per atom. ii. Find the average drift speed of the moving charges in the cylinder.
Please answer this question: An aluminum wire having a cross-sectional area of 2.10 ✕ 10−6 m2 carries a current of 6.00 A. The density of aluminum is 2.70 g/cm3. Assume each aluminum atom supplies one conduction electron per atom. Find the drift speed of the electrons in the wire. Please answer correctly!!!! Thank you so much in advance!

A copper wire has cross section area 0.002 m' and length of 400 m, what is the resistance of this copper wire? When a 200-V potential difference is applied over the wire, what is the current through the wire and what is the electric power? If the current is uniformly distributed, what is the current density? If the drift speed is 10 m/s, what is the number density of electrons in the wire? (Given copper's resistivity as 2x10 s2 m)....
You are working at a company that manufactures electrical wire. Gold is the most ductile of all metals: it can be stretched into incredibly long, thin wires. The company has developed a new technique that will stretch 1.00 g of gold into a wire of length L= 2.40 km and uniform diameter. a) What is 1 gm in kg, and what is the volume of 1 gm of gold? The mass density of gold ρ= 1.93 x 10^4 kg/m3. Watch...
If 1.11x1020 electrons flow through a cross section of a 2.96 mm diameter Gold wire in 5.53 s, then what is the drift speed of the electrons? (The density of conduction electrons in Gold is n = 5.90x1028 1/m3.) 4.94x10-2 mm/s (in mm/s)
