AI Customer ServiceFor the wire - any given current flowing through it must be associated with one and only one rate of heating. Now let''s think about what happens when we join these two separate ideas - when
AI Customer ServiceInternal Resistance depends on the ability of the battery to supply current. A discharged battery cannot simply supply current. When high current/low resistance is attached
AI Customer ServiceYes. When a battery is operating normally then current flows inside the battery from the negative terminal to the positive terminal.

AI Customer ServiceIndeed, the most power you can get out of a battery is into a resistor whose value equals the internal resistance of the battery. If so, the battery voltage is half of the nominal (e.g., 4.5 V) and the power wasted in heat is
AI Customer ServiceAlso, the maximum current that can be drawn from a battery is now reduced due to this internal resistance. If the value of I > I(0), then the value of V becomes negative, which
AI Customer ServiceThe emf is equal to the work done on the charge per unit charge (left(epsilon = frac{dW}{dq}right)) when there is no current flowing. Since the unit for work is the joule and

AI Customer ServiceInternal resistance in a battery refers to the amount of resistance that the battery's internal components, such as electrodes, electrolyte, and terminals, present to the flow of current within the battery. This resistance causes some of the electrical energy produced by the battery to be converted into heat, reducing
If the internal resistance of the battery cell is not provided by the manufacturer, as we’ll see in this article, using the discharge characteristics of the battery cell, we can calculate the internal resistance of the battery cell, for a specific state of charge value.
The function of a battery above relies on two chemical reactions to produce a flow of Electrons. These reactions are exothermic, meaning that heat Energy is given out by the cell as the Current flows. This energy is lost from the cell as waste heat. The more Current that flows through the cell, the more Energy that is lost as heat.
Or the internal resistance increases. This answers why the internal resistance of the battery depend upon whether the battery is charged or discharged. Generally, the nature of variation of internal resistance with the energy contained in the battery depends upon the type of the battery and also on other factors like temperature.
Internal Resistance depends on the ability of the battery to supply current. A discharged battery cannot simply supply current. When high current/low resistance is attached across it, voltage drops across the terminals. When battery is fully charged, it can supply high current while maintaining voltage across it, hence low internal resistance.
This resistance causes some of the electrical energy produced by the battery to be converted into heat, reducing the amount of available voltage and current that can be delivered to an external circuit. The internal resistance of a battery can be calculated by measuring the voltage drop that occurs when a known current is drawn from the battery.
