In a series circuit, if one of the light's filiments opens the bulb will go out, but along with that light every other device in the same circuit will stop operating.
Think of an electric light circuit, in your home, that is controlled by a switch. When the switch is turned off the light goes out. This is an example of a series circuit where ithe switch is in series with the lamp.
There are many. One example would be an item used in an electric circuit, like a bulb.
Useless is a non-example of practical.
An electric circuit is just a circle of electric wires who connect all sorts of resistances (everything that uses electricity is called a resistance) and an electric source. Example: a battery connected to three lights: (each R represents a bulb) I hope this helps!
A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.
A practical example is it's the reason the sky is blue.
Electric motor is an example of conversion of energy. Electric generator is another example.

An electric motor for example
A colloid is an example of a mixture. Specifically, colloids are mixtures in which the components do not separate. Mixtures in which the components do separate are known as suspensions.
water expansion is an example
The most familiar example of this is running an electric motor.
