Series circuit | التوصيل على التوالي
Series circuit which has only one path for the current to travel.
If a lamp 'blows' or a component is disconnected, all the components stop
working.
If you put more lamps into a series circuit the lamps will be dimmer than before.
Series circuits are useful if you want a warning that one of the components in the circuit has failed. They also use less wiring than parallel circuits.
