This is because current is decreased with higher resistance. Current equals voltage divided by resistance (i=v/r). So the higher the internal resistance, the lower the current output ability. Low internal resistance batteries are much better at supplying high current pulses.
The greater the internal resistance, the more significant the voltage drop. To illustrate this, consider a simple experiment with a AA cell. When connected to a 4 Ω resistor, the voltage across the battery terminals might drop from its VOC of 1.5V to around 1.45V. This drop is due to the battery’s internal resistance.
Current equals voltage divided by resistance (i=v/r). So the higher the internal resistance, the lower the current output ability. Low internal resistance batteries are much better at supplying high current pulses. Internal resistance also increases as the battery discharges.
Factors affecting a battery’s ability to act as an ideal voltage source include: Age of the battery: Older batteries tend to have higher internal resistance. Temperature: Extreme temperatures can affect the internal chemistry, leading to increased resistance. State of charge: A battery’s internal resistance can vary depending on its charge level.
Battery internal resistance is the opposition to the flow of current within the battery. For many years, batteries were often assumed to be ideal voltage sources. In simple terms, this means that the battery would always provide a constant voltage regardless of the load connected to it.
The electrodes and electrolytes aren't 100% conductive. So they will have some resistance (internal resistance) in them. Ideally, a battery should have 0Ω internal resistance. So during battery operation, all the voltage will be dropped across the element that the battery is powering instead of the battery dropping voltage across itself.
