Series of lights
Ammeter 1= 220 Bulb 1= 1.2
Ammeter 2=220 Bulb 2= 1.1
Battery=3.0
The current in ammeter 1 compared to ammeter 2 is the same. The voltage across bulb 1 and bulb 2 are different by 0.1. The voltage of bulb 1 plus bulb 2 compared to the battery voltage are different. current and voltage change mattering on how many ammeters or voltmeters there is.
