What does reversing the direction of the electron flow in the battery do?

The voltage measured across every component in the circuit would take on
the opposite polarity from what it was originally. If there are any diodes in
the circuit, then current might stop flowing in some branches where it formerly
existed, or start flowing in branches where there was no current before.

Nothing will happen. It requires two wires to complete the circuit. Electrical current travels from the battery terminal through the wire to a metal portion of the base of the lightbulb. The current then travels up through the filament wire which glows as the current travels through. The current then travels back down the other side of the filament wire to the base of the bulb and thus through the second wire back to source, which is the battery.

When a battery is intentionally short circuited, there is nothing in the in the electrical path to limit the current flow except the resistance of the conductor and the internal resistance of the battery. Both of these values are so small that their effects on the circuit are negligible. So if we assume the the resistance of the short circuit is 0 ohms (it will be almost 0 ohms in applied theory), then the current in the circuit will continue to rise until the conductor shorting the circuit or the battery itself is destroyed. This will happen extremely quickly and will potentially cause harm or death to any bystanders.
Again, do not attempt to short circuit a battery or any other electrical circuit unless you are trained and qualified to do so.

∙ 8y agoUnlike AC (alternate current), DC (direct current) as from a battery is directional. So changing the DC current to a motor would make the motor spin in reverse. An LED (light emitting diode) would not light up if the positive lead from the battery was changed to the negative pin on the LED..

What is the direction of current due to flow of electrons if it is not conventional current?
Electron flow is from negative to positive. Conventional current flow is from positive to negative.
What is the direction electron flow during the x ray exposure?
through the X-ray machine
What is the difference in the direction of the magnetic field produced around conductor by dc flow and ac flow?
The direction and amplitude of the magnetic field around a wire depend on the direction and amplitude of the current through the wire. When the wire carries DC, the direction and amplitude of the current in the wire are constant, so the direction and amplitude of the magnetic field around the wire are constant. When the wire carries AC, the direction of the current in the wire is periodically reversing and its amplitude typically changes, so the direction of the magnetic field around the wire is periodically reversing and its amplitude is typically changing.
When electrons are moving from negative pole to positive pole in the circuit then current in the circuit will be moving in which direction?
always current flow from the opposite direction of electron
How does the flow of current within the simple cell differ from that in a copper wire?
One terminal of a cell or battery is positive, while the other is negative. It is convenient to think of current as flowing from positive to negative. This is called conventional current. Current arrows in circuit diagrams always point in the conventional direction. However, you should be aware that this is the direction of flow for a positively-chargedparticle.In a copper wire, the charge carriers are electrons. Electrons are negatively-charged and therefore flow from negative to positive. This means that electron flow is opposite in direction to conventional current.
Is the direction of current through a battery always from negative to positive on the terminals?
Conventional current flow is from positive to negative. Electron flow is from negative to positive
What flow is equal to and opposite of electron flow?
The "flow of current" is considered to be in the opposite direction.
What is a electron flow in only one direction called?
A current.
What allows current to flow in one direction?
A diode is one of the fundamental building blocks of electronics. They allow the flow of electrons in one direction only. Thus are commonly used as rectifiers to turn ac voltages into dc. [A dry cell (mistakenly called a battery, which is a group of cells) will allow electron flow in one direction only, or rather, it will provide current flow in one direction. ]
What determine the direction of flow of charge?
Electro motive Force(E.M.F) of a battery determine the direction of Flow of Charges.
The expression alternating current refers to which form of energy?
Alternating current is a flow of electrical energy in which the direction of electron flow reverses periodically. The mains electricity in your house is likely Alternating Current. The other form is Direct Current, where the direction of electron flow is in one direction only. Such as the flow from the batteries in your flashlight.
Do Diodes have the ability to block electron flow in one direction and pass electrons in the opposite direction.?
yes
The battery determines the direction of flow of charge in a circuit?
Yes
Difference between electron flow and conventional current?
Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges), then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).
What is the direction of current due to flow of electrons if it is not conventional current?
Electron flow is from negative to positive. Conventional current flow is from positive to negative.
Why do 3 phase electric motors change direction?
because when you change any two phases you change the direction of the current flow in the windings so you end up reversing the direction of the induced flux and the direction in which it acts
What is the difference between electron flow direction and electric current flow direction?
the electrons flow from the region of low potential to region of high potential. the electric current also flow in this direction but for convention we took it as the flow of positive charge from region of low to high region potential.
