Finding the current through the battery
FAQ: Finding the current through the battery 1. How do I calculate the current through a battery? To calculate the current through a battery, you can use Ohm''s Law which states that current (I) is equal to voltage (V) divided by resistance (R). So, I = V/R. Make sure to use the correct units for voltage (volts) and resistance (ohms). 2.
When current flows from a battery, does voltage decrease?

DOE Explains...Batteries | Department of Energy
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.

voltage
$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).
