When you short a battery out, initially you do get the very high amperages you calculated. However, as the short continues, chemistry gets involved. Inside the battery you have two materials reacting with each other to provide the electrical energy. In the case of your example battery, NiMH, the reactions are:

batteries

The amps flowing through any wire has to deal with cross-sectional area or lets say thickness of the wire. The relation between them is given by: I=VenA; I is current, e is charge of an electron, n is no. of free electrons, and A is the cross sectional area of the conductor. So increasing the area increases the current through the wire.

Chapter 18

Electromotive Force and Current Within a battery, a chemical reaction occurs that transfers electrons from one terminal to another terminal. The maximum potential difference across the terminals is called the electromotive force (emf). The emf has units of Volts, e.g. a 12 V battery has an emf of 12 V

Design Principles and Development Status of Flexible Integrated Thin

The rapid advancement of wearable devices and flexible electronics has spurred an increasing need for high-performance, thin, lightweight, and flexible energy storage devices. In particular, thin and lightweight zinc-ion batteries require battery materials that possess exceptional flexibility and mechanical stability to accommodate complex deformations often encountered in

Lithium‐based batteries, history, current status, challenges, and

Restoration is achieved by applying a current to the battery in the opposite direction to the discharge current. Thus, the advantages of secondary batteries over primary batteries are their higher power densities, higher discharge rates, and reusability. 25, 26. For most of the 19th century batteries were the main source of electrical energy before the advent of

Current flow in batteries?

Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.

According to the USABC, the target lifespan of EV batteries is 15 years, over which the battery capacity should not drop below 80% of its initial as-manufactured capacity. 7 However, for instance, Tesla, an EV manufacturer,

What accelerates the electrons in the thin part of a current

Consider a thick wire that narrows for some part of its length, connected to the terminals of a battery, hence carrying some current. Presumably the electrons have to speed up as the wire gets thinner - if the current is constant everywhere, then if the wire cross-section is less, they have to go through faster in order for the same number of electrons to pass any

6 FAQs about [The battery line is thin and the current is large]

Why do battery terminals have a limiting resistance?

the current depends on the weakest link between + and -, which is not always the wire, usually it's the load, and on small batteries, the terminals themselves have considerable current-limiting resistance. You are absolutely right. The amps flowing through any wire has to deal with cross-sectional area or lets say thickness of the wire.

What happens when a battery is connected to a circuit?

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.

What happens if you connect a long wire to a battery?

When you connect a long wire to a battery, however, the current (the slow electron drift) starts almost instantaneously along the entire length of the wire. If the electrons were in a complete vacuum, rather than in the interior of a metal, they would accelerate as long as they were in an electric field.

What is the difference between voltage and current in a battery?

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. battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge.

What happens if you put a wire between a battery?

When you add a wire between the ends of the batteries, electrons can pass through the wire, driven by the voltage. This reduces the electrostatic force, so ions can pass through the electrolyte. As the battery is discharged, ions move from one electrode to the other, and the chemical reaction proceeds until one of the electrodes is used up.
