## Series circuit properties

1) Order of electric components

In a series circuit if we permute two different bulbs then each bulb maintains its brightness.

More generally:
In a series circuit, modifying the order of connection does not affect the way electric components operate.

2) Number of passive components

If we add a second bulb in a circuit including a bulb and a battery then the brightness decreases.
The brightness decreases even more if we add a third.
The result would be the same by adding a motor or a resistor instead of a bulb.

The more a series circuit includes passive components,  the more its bulbs get brighter.

3) Burnt out bulb or unscrewed bulb

If a bulb is burnt out or is unscrewed in a series circuit including multiple bulbs then all bulbs stop to shine.

If a bulb burns out then the filament is broken and when a lamp is unscrewed there is no more contact between the bulb and the socket.
In both cases the circuit is open and the electric current can not flow.

Conclusion: In a series circuit if a bulb is burned out or unscrewed other passive components do not work anymore.
