Please, no referring to other questions.A) A current of 1.70 A flows in a wire. How many electrons are flowing past any point in the wire per second?
A steady current of 36 mA exists in a wire. How many electrons pass any given point in the wire per second? electrons per second
If 1.0 A of current are passing through a wire how many electrons pass through a cross-section of the wire in 1.0 hours?
A total of 2.0 × 1013 electrons pass a given point in a wire in 15 s. What is the current in the wire? (e = 1.60 × 10-19 C) A- 1.3 mA B- 0.21 μA C- 3.2 μA D- 1.3 A
A very long, straight horizontal wire carries a current such that 8.15×1018 electrons per second pass any given point going from west to east. What is the magnitude of the magnetic field this wire produces at a point 5.00 cm directly above it? Express your answer with the appropriate units.
clearly explain everything
1. Given that the charge passing through a wire is given by q = 3¢t-0.5.9t2 find the current as a function of time and the current at time t = ls.
6E20 electrons pass a point in a wire in 1.5 seconds. What is the current in Amps?
Consider a copper wire with circular cross section with radius 0.5 mm, where the conduction electrons in the wire have drift velocity 1 mm/s. Copper has a density of 8960 kg/m3, and copper atoms have a mass of 63.5 amu (where 1 amu = 1.67 x 10−27 kg). (a) How many copper atoms are in one cubic meter of copper wire? (b) Assume each copper atom provides one conduction electron (that is, for each copper atom, one electron is able...
One long wire carries a current of 30A along the entire x axis. A second long wire carries a current of 40A perpendicular to the xy plane and passing through a point (0, 4, 0)m. What is the magnitude of the resulting magnetic field at the point y-2.0m on the y-axis?
How many electrons per second flow through a wire with a 27-pA current? (Recall that 1 pA = 10−12A and e=1.60×10−19C) Express your answer using two significant figures.
