batteries - Confusion about why voltage of a cell decreases as it

WebMay 3, 2016 · Internal Resistance When designing a circuit with a battery, we often assume that the battery is an ideal voltage source. This means that no matter how much or little load we attach to the battery, the voltage at the source's terminals will always stay the same. WebThis resistance is called the internal resistance of the cell. A cell can be thought of as a source of electromotive force (EMF) with a resistor connected in series. When a load …
