00:00Hi friends, every day is a new opportunity to learn and grow.
00:06When we hold an object, we don't feel anything.
00:10That's because the object is neutral.
00:14Every object is composed of atoms with positive and negative charges in the form of electrons and protons in equal numbers.
00:22Therefore, every object is naturally neutral.
00:30This object can become electrically charged due to the transfer of negative charges.
00:38When electrons are added to an object, the object becomes negatively charged.
00:44Our hands will feel a slight shock.
00:54When electrons are extracted from an object, the object becomes positively charged.
01:02Our hands will also feel the same shock.
01:12You might ask, why don't we add or extract positive charges?
01:16That's because positive charges are part of the atomic nucleus.
01:20Protons are tightly bound in the atomic nucleus by the nuclear binding force.
01:26While electrons are only bound by the Coulomb force.
01:30This is a simple concept why an object can be electrically charged.
01:36Simply put, a negatively charged object will have an excess of electrons, while a positively charged object will have a deficiency of electrons.
01:46Happy learning everyone!
