When connecting multiple loads to a single battery, how can one calculate the total current output of the battery? Is it possible to simply add the current across all loads, or is the current of the battery equivalent to the current of only one load? Please take the example below as a simple way to visualize the scenario so that it may be answered in a simple and effective manner.
Say I have a battery and three LED lamps connected to it. If, for instance, each lamp is rated at 100 milliAmps, what is the total current output of the battery at a given point in time?
A) 100 mA
B) 300 mA
If it depends on parallel or series, please explain what would happen in either situation.
