In series circuits, the current is the ... supply is shared between the components. A parallel circuit showing two bulbs, a switch and a cell. An ammeter takes readings near the cell.

The current flowing in a parallel circuit can be investigated by connecting the circuit below. Once more, put one ammeter in position ... In the diagram, 6 A flows through the cell.

What do series and parallel circuits have to do with Christmas lights ... This is known as an ammeter, and it measures the current in Amperes by connecting in series with the circuit.
