Does the internal resistance increase as the voltage of the battery goes up? For example does a 1.5V battery have a lower internal resistance than a battery of 9V? Made from the same manafacture.
I think you meant AAAA, not AAA.Hello,
A 9 Volts battery consists of 6 AAA size batteries.
As the active area is smaller of those AAA cells, the internal resistance is higher.
The AA battery has a larger active area, so the internal resistance is lower.

In a 9V battery made up of 6 AAAA cells in series, the resistance will be 6 times that of a single AAAA.Does the internal resistance increase as the voltage of the battery goes up? For example does a 1.5V battery have a lower internal resistance than a battery of 9V? Made from the same manafacture.
Some of the newer "9V" batteries I have taken apart use six short "stubby" cells instead of the long skinny ones.I think you meant AAAA, not AAA.
There are other ways of making a PP3 9V battery. See the Wikipedia article.
