Simple Series Circuit. The amount of current is the same through any component in a series circuit. Series circuits are useful if you want a warning that one of the.
Some old christmas lights are connected in series. In this simple series circuit a 9 volt battery provides 3 volts across each lamp. Experiment with series circuits and parallel circuits.
In a series circuit if a lamp breaks or a component is disconnected the circuit is broken and all the components stop working.
This is usually a bit more challenging. The total resistance of any series circuit is equal to the sum of the individual resistances. The main disadvantage of a series circuit is that when one device fails the current in the whole circuit stops. Some old christmas lights are connected in series.
