Finding internal resistance of battery

WebAug 23, 2024 · For example, a battery which is still 50% charged, but has too much internal resistance to supply the required current and terminal voltage, might not be considered suitable. Here we are more interested in defining some maximum acceptable internal resistance, and finding the charge state corresponding to that. WebSep 12, 2024 · The analysis above gave an expression for current when internal resistance is taken into account. Once the current is found, the terminal voltage can be calculated by using the equation V t e r m i n a l = ϵ − I r. Once current is found, we can also find the power dissipated by the resistor.
