Dear forum,
I am trying to characterize the battery requirements for an existing battery-powered lighting product. Specifically, I am trying to figure out how much current the LED uses when at maximum setting, v. the rest of the electronics.
I inserted the multimeter in series at the positive battery terminal and got a result of 1.3 A. Then I inserted the multimeter in series at the red wire exiting the LED and got a result of 1.45A.
I am primarily a mechanical engineer and product designer with a very limited electronics background. Based on my limited understanding the current at the LED should have been less than or equal to the current at the positive battery terminal.
Can anyone suggest what I might be doing wrong?
