Question

An electric current flows through a parallel circuit. Which units tell you about the amount of electrons traveling in the circuit?
a. ohms
b. amps
c. volts

Answer 1

'Ampere' is the unit of current.  That's the rate at which
electrons travel in the circuit ... the number of electrons
every second.  If you wanted the actual amount or number
of electrons, you'd need to know the length of time too.

It doesn't matter whether we're talking about a parallel or
series circuit.
