Electric current

Question

it’s approximately 4.0×10^22 electrons pass a given point in a circuit every hour then the electric current at this point is?

a. 1.8A

b. 3.2A

c. 9x10^44 A

d. 6.9x10^37 A

Answer 1

Current is the amount of charge passing through per second.

Each electron has the change of about 1.6×10^-19C.

And we have 4×10²² of them every 3600 seconds, which is

4×10²²×1.6×10^-19 C / 3600 s = 1.8 C/s = 1.8 A
