The Lemon
Battery
The lemon battery is a type of electrical
battery that is
commonly made for school science projects because it illustrates a battery's
main components. Typically, a piece of zinc metal and a
piece of copper metal are
inserted into a lemon. Everyday objects such asgalvanized nails and copper pennies can be used for the zinc and for the
copper. A single lemon is usually studied using an electricalmeter. Several
lemons can be wired together to form a more powerful battery that will power a
light-emitting diode, a buzzer, a digital clock.
The lemon battery is similar to the first electrical battery invented in 1800 by Alessandro Volta, who used brine (salt water)
instead of lemon juice. The lemon battery is described in some textbooks in
order to illustrate the type of chemical reaction (oxidation-reduction) that occurs in batteries. The zinc and copper are called the electrodes, and the
juice inside the lemon is called the electrolyte. There are
many variations of the lemon cell that use different fruits (or liquids) as
electrolytes and metals other than zinc and copper as electrodes.
Lemon contains vitamin C, citric acid, amino acids (tryptophan,
lysine), essential oils (sitral, limonene, fe Landen, lemon camphor, kadinen,
and niidehida), glikolisa, citric acid, sulfur and vitamin B1 (thiamine).
But we never expected, it turns out lemon can also be used to make
batteries. Chemical substances present in the lemon can be converted into
electrical energy in a circuit voltaic cell.arichandrawardani.wordpress.com http://vidyakirana.blogspot.com/
