Question

2. The current in a wire is 4.5 A.
a. How many coulombs per second are going through the wire?
b. How many electrons per second are going through the wire?​

Answer 1

Answer:

a ) the amount of electrical charge flowing through a wire per second. Current is measured in Amperes: One ampere is one coulomb per second. The symbol for current is an i.

b) The unit we use to measure current is the ampere, usually pronounced in shortened form as "amp". So, saying that 1 amp is flowing through a wire is equivalent to saying 6.24x1018 electrons are flowing down the wire every second
