When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
When a battery is connected to an electrical circuit, electrons flow from the anode to the cathode through the electrolyte, producing a voltage difference between the two electrodes. The amount of voltage produced depends on the type of chemical reaction taking place inside the battery.
With this analogy, it is plainly obvious why both the positive and negative ends of a battery must be connected in a circuit. If, say, you connect only the negative electrode to ground, there is no current because there is no electricity coming in on the positive electrode that can be pumped out.
In your battery example, there is no return current path so no current will flow. There is obviously a more deep physics reason for why this works but as the question asked for a simple answer I'll skip the math, google Maxwell's Equations and how they are used in the derivation of Kirchhoff's voltage law.
When a battery is connected to an external circuit, such as a flashlight, the electrons flow from the negative electrode to the positive electrode, producing an electric current. This process is called oxidation-reduction (or redox for short). The chemical reactions inside the battery generate an electric current when connected to an external circuit.
Batteries generate direct current (DC), a type of electrical current that flows in a single direction. In this article, we’ll delve into the fascinating world of batteries and explore the inner workings of the current they produce. So, let’s dive in and uncover the secrets behind this essential source of power.
Physics Tutorial: Ohm''s Law and the V-I-R Relationship
The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current. And the greater the resistance, the less the current. Charge flows at the greatest rates when the ...

Current flow in batteries?
However, current more than likely won''t (depending upon the age/use of the battery). The reason why is because the voltage potential difference - the "excess holes on the positive end" and the "excess electrons on the negative end" - is relative to a given battery. There are excess electrons/holes on the ends of a given battery with respect to ...

These electrons then flow through a circuit, creating an electric current. One of the primary components of a battery cell is an electrolyte, a substance that conducts electricity. When a battery is connected to a circuit, chemical reactions occur within the cell. These reactions cause a buildup of electrons at the negative terminal and a deficiency of electrons at the …

Why Do Batteries Get Heated?
So batteries are not perfect devices and are not perfect conductors. Within every battery there is some internal resistance due to the chemical composition of the battery. Resistance opposes the flow of current, which is displayed in ohms law, I= V/R. Current is the flow of electrons. Resistance opposes this flow of electrons and creates ...

The reason batteries are made this way is because in order for the anode electrolyte and the cathode electrolyte to come to thermochemical equilibrium, there has to be a transfer of both electrons and ions.

The positive of battery 2 is now at 18V relative to ground because it is always 9V above its own negative terminal at equilibrium. As for a short circuit, in order to get a short circuit, I have to provide a complete circular path for current to flow through. I can do this by adding another wire between any two terminals.
