When Thales rubbed amber with silk, he observed that the amber attracted small objects like feathers and hair. This phenomenon is known as static electricity, where the friction between the amber and silk causes the transfer of electrons, giving the amber a temporary charged property.
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.
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.
Thales discovered static electricity by rubbing a peice of amber against a silk cloth.
the silk will rub of the electrons on the silk, leaving the glass positively charged
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.
Thales of Miletus is said to have discovered static electricity around 600 BCE. He observed that when amber was rubbed with fur, it attracted lightweight objects like feathers.
The silk picked up positive charges.
The Physicist who said first that the charge on a glass rod rubbed with silk is positive was Michael Faraday.
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 a plastic rod is rubbed with a silk cloth, electrons are transferred from the silk to the plastic rod. This results in the plastic rod becoming negatively charged and the silk cloth becoming positively charged. This effect is known as triboelectric charging.
A balloon rubbed in hair becomes negatively charged due to gaining excess electrons from the hair. On the other hand, a glass rod rubbed with silk becomes positively charged as it loses electrons to the silk.
