The Magic of Batteries
Many things use batteries to work. For
example: calculator, torch (flash light), clock, watch, cell phone, remote control, radio, toys, camera, door
bell, small TV, telephone, laptop, etc.
The first battery was made in 1800 by
Alesandro Volta (Italia).
Batteries have different shapes and size: big
or small, thick or thin, rectangular or cylindrical batteries.
These are the different shapes of
Batteries are diferent from one another. The big battery has
bigger power than the small one.
A batetry has 2 ends: positive (+) end and
negative (-) end.
To make the things work, put the + end of a
battery to the + sign in the battery slot of the things. Put the - end of battery to the - sign and joined to the
spring in the battery slot.
To make a simple circuit, we need a battery, a
wire, and a bulb.
To light up a bulb, we have to connect the
parts of the circuit correctly.
When the parts of the circuit are not
connected correctly, the bulb does not light up.
A circuit with more than one battery will
light up the bulb brighter than the circuit with one battery only.
Thomas Alfa Edison was the great inventor. He
invented bulb that could stand for 40 hours in 1879. In 1880 he invented the modern electricity distribution
