Look at is from a waterfall point of view. If there is more current, is the water flowing faster or is there more water? (If you do not catch on, there is more water and for your question, more electrons.)
Electroncs cannot travel faster, they travel at the same speed, and they reach destination faster or slower depending on resistance.

Does electricity get used up when flowing in a circuit?
The free electrons flowing in the circuit decrease.
The unit of current in which 6240000000000000000 electrons flow past a given point in a circuit in one second is the?
The amount of current is measured in units called amperes or amps. One ampere of current is equal to the charge of 6,240,000,000,000,000,000 electrons flowing past a given point in a circuit per second Its in the Penn Foster Book.
What happens to the current flowing in the ring main as more bulbs are turned on at night?
As more light bulbs are added in a series circuit, the effective resistance of the circuit increases. That causes the current leaving the source to decrease.
A W bulb and a W bulb are connected in series in a circuit Which bulb has the greater current flowing in it?
A series circuit is where there is only one path for the current. As a result, and as a direct consequence of Kirchoff's current law, the current at every point in a series circuit is the same. The two bulbs have the same current flowing through them.
When does current stop flowing in a circuit?
Current flows in a circuit when there is a difference in electronic potential between two points.
When electric current is flowing in a circuit if the voltage applied to the circuit is increased the?
Correct Answer= "the current will increase"
Is true if there is voltage in circuit there must be electrons flowing through the circuit.?
No. For electrons to flow, you need a current.
Is somthing that flows through an electric circuit an eletrical current?
Yes. Current consists of electrons flowing in a circuit.
What force keep current flowing?
Voltage is the pressure that moves the electrons (current) through a circuit.
Does electricity get used up when flowing in a circuit?
The free electrons flowing in the circuit decrease.
What is a circuit called if its operating and the current is flowing?
This is called a closed circuit. If current was not flowing, it would be open.
What goes around a circuit?
Charge, in the form of electrons, flow through a circuit. This is called electric current. 1 amp = 1 coulomb of charge per second flowing past a point in the circuit.
What kind of force keeps current flowing in a circuit?
EMF (voltage) is the force that keeps current flowing in a circuit.
Why is it that the current flowing through a parallel circuit is the different in all parts of the circuit?
Because there is many path for flowing current through circuit.
When is the current flowing in a circuit said to be very small?
When the current flowing in a circuit is very small the resistance will be very high.
How does the increasing the voltage in a circuit affect the energy of the electrons flowing in the circuit?
"How does increasing the voltage in a circuit affect the energy of the electrons flowing in the current?" Answer: The charge of an electron is constant. Every electron has a charge of something like 1.6 x 10^-19 coulombs. (The mass of an electron is also constant which will be important below). When the current in a simple direct-current electrical circuit is 1.0 Ampere there are 6.25 X 10^+18 electrons/second (or 1.0 coulomb of charge) flowing past a given point in the circuit (this is by definition or convention). The voltage (V) is equal to the current (I) times the resistance (R), or V=IR. So, in a simple direct current circuit where the resistance is constant (we will just assume that for the sake of simplicity), if we increase the voltage, the current must increase proportionately. This means the total charge passing a given point in the circuit must increase. This means that more electrons must pass a given point in the curcuit every second. Since the charge of every individual electron is constant there must be more electrons moving past a given point every second.What actually happens to the energy of the electrons flowing in the circuit depends on the geometry of the circuit. If the electrons are forced to travel in single-file (like cars on a one lane road), then in order for more of them to pass a given point every second, their velocity must increase. In this case, their energy would also increase according to the formula for kinetic energy (KE) of a moving particle KE=1/2MV^+2 (or one half the mass (M) times the velocity (V) squared). (This is where we have to remember that electrons are particles with constant mass too.) In this case, the energy increases with the square of the velocity of the moving electrons. However, if the electrons still travel at the same speed but on different paths (like cars on a multi-lane highway) so that more of them can get past a given point every second, then their energy doesn't change. In reality the resistance (R) also generally increases with an increase in voltage (V) so the current (I) may not increase in direct proportion to the voltage but the current will generally increase until too much heat and resistance occurs. The heat generated by such a circuit is proportional to the square of the current which is pretty dramatic.
