What happens if you remove a battery from a circuit?

If the circuit is powered by the battery, it will stop working. If it is powered by another source, chances are it will continue working unaffected, but it depends on whether it still requires the battery to be plugged in even with an AC mains power running to it.

What happens to the electric charges when the wire is disconnected from the battery?

If the wires to the battery are disconnected, the charge remains on the plates — and the voltage across the plates remains the same. If the wires are connected to each other, current will flow and the capacitor will discharge.

What happens to the electricity as it leaves the battery and moves through the circuit?

As the positive test charge moves through the external circuit from the positive terminal to the negative terminal, it decreases its electric potential energy and thus is at low potential by the time it returns to the negative terminal.

Can a car move without a battery?

Yes, an automobile can run without a battery, if the alternator is large enough to support all of the electrical needs. However, it’s starting the automobile that would be much more convenient in life if one had a battery.

Will current flow through an open disconnected circuit Why or why not?

In the open circuit the current can not flow from one end of the power source to the other. Because of this there is no current flow, and therefore the light does not turn on. Why didn’t the light bulb turn on in the open circuit? Current follows the path of ‘least resistance’ Resistance is provided by the light bulb.

What way do electrons flow in a circuit?

positive
The direction of free electron flow is from the negative terminal, through the conductor, to the positive terminal. The direction of conventional current is the direction marked on all circuit diagrams. The symbol for electric current is I.

How does electricity move through a circuit?

The particles that carry charge through wires in a circuit are mobile electrons. The electric field direction within a circuit is by definition the direction that positive test charges are pushed. Thus, these negatively charged electrons move in the direction opposite the electric field.

How long can a car run without battery?

Unless your battery was also fscked you should’ve been able to go a lot longer than 5 minutes before your engine died. and in response to the question, yes a car can run with a dead battery, or a dead alternator (as long as the battery still has some charge), but not if both are dead.

How do batteries work with no external circuit?

With no external circuit present a chemical process within a battery moves mobile electrons within the battery to produce a surplus of electrons on the negative terminal and a deficit of electrons on the positive terminal.

Why don’t electrons move in a battery?

The reason is that an electron can’t move from one side to the other inside the battery without a chemical reaction occurring. In other words, inside the battery plain electrons can’t travel around because it takes too much energy to put a plain electron in solution.

How do batteries pump electrons from positive to negative?

The potential difference causes the circuit’s electrons to move in the direction of the positive terminal and then the battery does work to “pump” them to the negative terminal. The electrons just circle around the circuit.

What happens when electrons leave the top plate of a circuit?

When electrons leave the top plate it then has a net positive charge which will tract electron to the bottom plate which thus becomes negatively charged. So there is a movement of electrons from the top plate (which becomes positive) through the voltage source and onto the bottom plate (which becomes negative).
