The passing charges is called, "Current", and the rate of those charges is measured in "Amperes", capitalized because the word is taken from a person's name.
The common electrical units are:
Electromotive Force, or EMF. Measured in Volts.
Current. Measured in Amperes.
Resistance. Measured in ohms.
the rate in which electric charges move through a conductor is current.
The number of wavelengths that pass a point in each second is the frequency, measured in Hertz (Hz).

well, current is the movement of free electrons so if you break a point in the wire you effectively stop the electrons from flowing as the electrons need to be touching each other in order to pass on energy or charge. The reason why if there is a gap in the circuit the electrons dont just jump it is because of resistance of air as the electrons in air are not free to flow they are not conduction electrons unlike in a metal such as copper wire.
Electric current is described in units of 'Amperes' . It's a direct expression of the number of electrons that pass a point in the circuit every second. "1 Ampere" is something like 6,250,000,000,000,000,000 electrons per second.
Current is measured in C.s-1 thus the amount of coulomb per second therefore in one minute there is: (60s x 4C.s-1) = 240Coulomb charger past any point in the resistor(or circuit). There is 6.241 509 629 152 65 × 1018 electrons in one coulomb charge (see why we use coulomb in stead of electrons!) thus there will pass 6.241 509 629 152 65 × 1018 X 240 electrons through the resistor in one minute if one amp current is present, i.e. = 149 762 310 960 000 000 000 or 1.49x1020
Freqency in electromagnetic waves is the number of waves that pass one point in a second.
Electric current is the flow of charge from one place to another. Charge is carried by electrons, so current can be defined as the number of electrons per second that pass through a given area.

By Flowing of Free or Conduction Electrons
Any electrons flowing through a superconductor will show up as a regular electric current.
Charge is the number of electrons that pass a point in a circuit per second. Hence Q=It

An infinite number of lines can pass through a point.
Electric current is described in units of 'Amperes' . It's a direct expression of the number of electrons that pass a point in the circuit every second. "1 Ampere" is something like 6,250,000,000,000,000,000 electrons per second.
Frequency.
That is twice the frequency. Frequency is equal to the number of complete cycles which pass a point per second.
If you divide the charge by the time, you get the average current (in amperes).
