A student connects a circuit consisting of a 3.0 V battery, a switch, two identical lamps (lamp 1 and lamp 2), and two ammeters, all connected sequentially in a single loop.
Give the name for the way the components are connected in this circuit.
The resistance of each lamp is 6.0 Ω. Calculate the combined resistance of the two lamps.
When the switch is closed, calculate the current measured by the ammeters.
