Current in parallel circuits The current flowing in a parallel circuit can be investigated by connecting the circuit below. Once more, put one ammeter in position A 1 and record the reading in a ...

In National 4 Physics examine the current and voltage in series and parallel circuits to formulate rules and determine unknown values.

If you wanted, you can make a similar circuit with 10 or 20 bulbs. Just connect them all in a line so that the same current goes through each one. This is a series connection.
