Key Takeaways Voltage vs. Current: Voltage can be present in a battery without significant current (amps). Battery Health Indicators: Voltage alone is not a reliable indicator of a battery’s ability to deliver power. Internal Resistance: High internal resistance can lead to a situation where a battery shows voltage but no current.
If there is no current flowing out of the battery, ohm law says that there is no voltage drop in R1. Thus the output voltage of the battery is V0: the nominal voltage of your battery. You are talking about a "singularity" here ...
Physical voltage sources, such as a 1.5V battery, cannot supply unlimited current and, in fact, produce a finite current when short-circuited. So, we typically model a physical battery by placing a resistor in series with the voltage source. But this is the topic of another question. The battery voltage is defined by its chemistry.
A battery is an approximate voltage source, not a resistor and thus does not obey Ohm's law. For an ideal voltage source, the voltage across is independent of the current through; the voltage across is what it is regardless of the value of the current through.
It’s the opposition within the battery to the flow of current. As batteries age or undergo multiple charge-discharge cycles, their internal resistance increases. This increase can lead to a situation where, despite showing adequate voltage, the battery can’t deliver enough current, resulting in no effective amperage.
Voltage: The battery voltage is the voltage difference between the anode and cathode. Different battery chemistries have different rated voltages; for example, Li-ion cells have a rated voltage of 3.7V, while alkaline cells have a rated voltage of about 1.5V. Higher voltages result in higher capacity and output power.
