If a current of 1.28 amps moves in a wire, how many electrons pass by any point in the wire each second?  Express your answer in exponential notation.

A current of 3.4 A flows through a battery for 2 minutes. How much charge passes through the battery in that time?

A 300-km-long high-voltage transmission line 2.0 cm in diameter carries a steady current of 1,240 A. If the conductor is copper with a free charge density of 8.5  1028 electrons per cubic meter, how many years does it take one electron to travel the full length of the cable? (Use 3.156  107 for the number of seconds in a year.) ?yr

What is the current travelling through a cellphone charger when 0.20 mC of electronspass a point in 0.75 min? Answer in amperes and microamperes (μA).

A current of 4.4 A flows for 16.0 s through a conductor. Calculate the number of electrons that pass through a point in the conductor during this time. Answer format: 1.23e+45

A conductor has a cross-sectional area of 2.3x10-6 m2 and the number of free electrons per unit volume is 8.5 x1028 electron/m³. When the current is 6.2 A, find the drift speed (in mm/s) of the electrons. Use the charge of the electron to be 1.6×10-19 c. Select one: А. 0.20 B. 0.14 C. 0.26 D. 26.02 Е. 19.82

A wire has a current of 6.0 mA in it. How do we determine how many electrons pass a given point in a minute?
