batteries
Le''s assume the load resistance is 4.5ohm and battery voltage is 9v, so current flow through the loop is 2amp; for the same load resistance(not be changed in any variation of voltage and current), if the battery voltage is 18v the current flow through the loop becomes 18v/4.5ohm=4amp. if I am wrong please give me feed back.

Relation between battery cell capacity & internal resistance
Is more correct to say that internal resistance is related to battery discharge current. Indeed, a battery with higher discharge current will have a smaller internal resistance. For example, a LiPo prismatic cell of 3000mAh used to have a bigger discharge current than a cylindrical LiIon with the same capacity.

As the battery warms up the heat produced by electrolyte resistance will reduce, slowing the internal temperature rise. However the reduced voltage drop also results in higher terminal voltage, so the load may more draw current (or the same, or less, depending on what type of circuit the battery is powering).

Why is current the same on both sides of a battery?
In a battery, current is the same on both sides because it forms a closed circuit. The battery’s internal chemical energy converts to electrical energy, generating a voltage difference between terminals. This voltage difference drives current through the circuit, from one terminal to another, and back through the battery.
How does a battery produce electricity?
A battery produces an electric current when it is connected to a circuit. The current is produced by the movement of electrons through the battery’s electrodes and into the external circuit. The amount of current produced by a battery depends on the type of battery, its age, and its operating conditions. Is a Battery AC Or DC Current?
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.
How does voltage affect a battery?
This voltage difference drives current through the circuit, from one terminal to another, and back through the battery. As the current flows, the same amount of charge passes through both sides of the battery, ensuring equal current on both sides.
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.
Does a battery provide current?
Yes, a battery provides current. A battery is a device that stores energy and converts it into electricity. It consists of one or more electrochemical cells that convert chemical energy into electrical energy. How Much Current is in a Battery?
