The unit of measure for electron flow per second is the Amp. It takes 6.2 E18 electrons per second to make one Ampere.
Current measures the flow of electrons through a circuit and voltage basically measure the amount of available electrons.
Resistance is the ability to regulate the amount of charge flowing in a circuit.
It makes no difference whether the circuit is parallel, series or complex. The number of electrons travelling (or oscillating back and forth for AC) is determined by the current (amps). 1 amp = 1 coulomb/second. 1 coulomb = the charge represented by 6.24150962915265 x 1018 electrons. The current in each leg of a parallel circuit has to be worked out separately.
An ammeter measures the amount of current flowing in a circuit
A resistor is a device that resists the flow of electricity in a circuit. It is used to control the amount of current flowing through the circuit by providing a specific amount of resistance.
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
Strength of current refers to the amount of electric charge flowing through a circuit per unit of time. It is measured in amperes (A) and represents the rate of flow of electric charge in a circuit. A higher current strength indicates a larger flow of charge through the circuit.
A variable resistor can be used to control the current in a circuit by adjusting its resistance. By changing the resistance value, the amount of current flowing through the circuit can be regulated.
Electricity is measured by amperes, not by counting electrons. And of course, different circuits have different numbers of amperes moving through them anyway. However, for a very rough estimate, there would normally be something on the order of a trillion trillion electrons involved in a normal electric current. Individual electrons are very small and very numerous.

Resistance
Volts = Current x Resistance. The voltage is where the potential resides for the amount of current flowing through a resistance. Think about the voltage as a potential source of electrons that then flow through a circuit depending on the Load, or resistance in this example.
