Which ammeter will have the biggest reading A series circuit powered by a battery consisting of an ammeter (ammeter 1) a lamp a second ammeter (ammeter 2) and another lamp.?

In a series circuit, the current is the same throughout all components. Therefore, both ammeter 1 and ammeter 2 will read the same current, as they are measuring the same flow of electrons in the circuit. The readings on both ammeters will be equal, so neither will have a bigger reading. The voltage drop across the lamps may differ, but that does not affect the ammeter readings.
