Thales of Miletus, a Greek philosopher, discovered that rubbing amber with silk created an electric charge in the amber which caused objects to be attracted to it. If rubbed enough, it created a spark, much like we receive when we walk on carpet and touch a doorknob and see, hear and feel the spark.

Why is Electricity called Electricity?
It comes from the Greek word "electron." However, to the Greeks that word didn't mean what it does to us; it meant the material we call amber. It's called that because one of the first noticed electrical phenomena was that if you rubbed a piece of amber with a cloth you could build up a static charge and make a small spark.

Explain clearly what happened when Thales rubbed the amber with the silk cloth?
When Thales rubbed the amber with the silk cloth, he was observing the phenomenon of static electricity. The friction between the amber and silk caused the transfer of electrons, with the amber becoming negatively charged and the silk becoming positively charged. This separation of charges created an electric field around the amber, leading to the attraction of lightweight objects like feathers or small pieces of paper. This experiment marked one of the earliest recorded observations of electricity and laid the foundation for the study of electromagnetism.
Who discovered static electricity in 600 BC?
Thales of Miletus, an ancient Greek philosopher, is often credited with discovering static electricity around 600 BC. Thales observed that when amber was rubbed with fur, it gained the ability to attract lightweight objects like feathers.
When did thales of milletus discover electricity?
Thales discovered static electricity by rubbing a peice of amber against a silk cloth.
What happened when thale rubbed the amber with silk cloth?
when amber is rubbed with silk cloth +ve charge comes on silk cloth and -ve on amber due to interaction between their molecules, so is that when we comb our hairs , then -ve charge comes on comb and +ve on hairs,so when we bring silk cloth near the comb they attract each other due to 'ving opposite charges
What is the charge on a piece of rubbed amber?
Friction strips electrons so the rubbed amber would take on a negative charge. Actually, friction causes charges to shift. Charges are indeed stripped from something, but they are collected up by something else. Amber does, indeed, become negatively charged by rubbing it with, say, fur. The phenomon is called triboelectric effect. And a link is provided.
Who invented the electrosatic generator?
The Greeks first wrote about static electricity generation. A silk cloth rubbed on an amber rod.
When was Greek static electricity found?
over 2500 years ago when they rubbed amber with cloth it attracted small objects
What will happened to the sand if you placed the balloon rubbed with woolen cloth near it?
the sand would stand up
What kind of charge is the cloth left with when rubbed against perspex?
The cloth is left with a negative charge when rubbed against perspex due to transfer of electrons from the perspex to the cloth.
Which charge does ebonite rod acquire when rubbed with woollen cloth?
The ebonite rod acquires a negative charge when rubbed with woolen cloth because electrons are transferred from the woolen cloth to the ebonite rod.
What kind of electricity does the balloon have after it was rubbed on the woolen cloth?
The balloon will have static electricity after being rubbed on the woolen cloth. This results from the transfer of electrons between the balloon and the cloth, causing the balloon to become negatively charged.
When a glass rod is rubbed with a silk cloth which substance looses electron?
The glass rod loses electrons when rubbed with a silk cloth. This leaves the glass rod positively charged as it loses negative electrons to the silk cloth through friction.
