Static Electricity Basics: Charge Separation | Triboelectric Series | Induced Charges (NSO | ICSE)

Описание: Mayank Bomb explains Charge Separation
===============
When the plastic ruler is rubbed on hair, electrons jump from hair to ruler- Mayank explains the physics behind the "magic". We start with atoms and then create charge separation.

When two materials are rubbed one of them gets positive charge while other becomes negative charged.

When Two Objects are Rubbed
=========================
Electrons are happier in certain materials than others.
Materials can either give electrons and become (+) or attract electrons and become (−).
Triboelectric series ranks materials according to decreasing tendency to gain electrons/increasing tendency to loose electrons.

Triboelectric Series
================
Triboelectric Series lists materials, from most tendency to become positive (+) to materials which become negative (−).
At the top is air with greatest tendency for giving up electrons and becoming highly positive (+) in charge
Cotton and steel have tendency to remain neutral
At the bottom is Teflon with greatest tendency of becoming highly negative (−) in charge

Common Materials to Remember
==========================
Positive Charge - Negative Charge
Glass rod - Silk
Woollen cloth/Fur - Ebonite, Amber, Rubber
Woollen cloth - Plastic
Dry Hair - Plastic comb/Balloon

Induced Charges
==============
We then understand the idea of induced charges which form the basis for many physics experiments including one we do in this video- rubbing a plastic ruler against hair to make it lift some paper bits.
