Electricity
Electricity is the set of physical phenomena associated with the presence and flow of electric charge
The movement of electric charge is known as an electric current
An electric circuit is an interconnection of electric components such that electric charge is made to flow along the CLOSE curcuit, usually to perform some task.
It is a device that produces visible light by the flow of electric current
Mainly used in the 19th centery
It consist of
Tungsten
metal tip
glass cover
metal case
four types of arrangement
bulb in parallel
bulb in series
battery in parallel
battery in series
The battery can last longer but the brightness would not increase when new battery in parallel is added.
The battery would last shorter but the brightness would increase every time new battery is added until it fuse.
when both the end of battery is connected to the end of the same wire, a short curcuit will occured
It is dangerous to touched an exposed wire and you might get seriously injured.
When too much battery is connected to a curcuit, the bulb might fuse
When bulb is added in series, the brightness would decrease.
When bulb is added in parallel, the brightness would remain but the battery would last shorter
