This is a GCSE Revision video about electric charge and static electricity. It explains what causes charge, how two different charges interact, and the basics of electric fields. It tells you how to produce an electrostatic charge and the differences between conductors and insulators.

What about earth and neutrallization
@lovattphysics6366
@lovattphysics6366 5 жыл бұрын
Hasnain Mughal You can think of Earth as always being neutral (as in it never has any charge). If something is negatively charged, the electrons are repelling each other and so if you connect that to Earth, the electrons will repel each other and travel down the earth cable until they are balanced with the positive charges in the object again, neutralizing the negative charge. The same happens if you connect a positively charged object to earth, except this time the electrons travel from earth into the object, neutralising it. Hope that helps!

why is static electricity not formed between a conductor and an insulator?
@lovattphysics6366
@lovattphysics6366 5 жыл бұрын
Jumana Mahmud remember a conductor can conduct electricity, which means electrons can move through it. So if you rubbed a conductor and an insulator together and electrons started to build up in the insulator, they would just move through the conductor and balance themselves out again. That’s why you only get static electricity when you have two insulators - the electrons cant move back to balance the charges. Hope that helps!

@@lovattphysics6366 alright so let's take two insulators and rub them. how do these tightly bound electrons from one insulator hop on to the other insulator on first place.
@lovattphysics6366
@lovattphysics6366 5 жыл бұрын
shan z good question. When you are rubbing two different insulators together, one of them will attract electrons slightly more strongly than the other, because all nuclei are slightly different. So the electrons move across to the material that is attracting them more strongly. If you rub two insulators of the same material together, this wouldn’t happen because they both attract electrons equally. Hope that helps!

So basically if electrons flow from the jumper to the rod... You have just created a current! and that would mean that you took the electrical charge and converted it to an electrical current by rubbing the rod against the jumper, only to store the electrical current as a static charge.... Hmmm well that makes sense because there's no such thing as static electricity but if you are saying static charge!... yeah, that makes plenty of sense... But why would anyone say static electricity? Electricity can only be electricity if there's a current, otherwise it's nothing more than a charge! The two are definitely related but they are different... Maybe you should take a closer look at the topic because I think that you have misunderstood something somewhere...

Peter Milanovski static electricity is a common term for the storage of static charge. There will be a small current when electrons move from one place to another, yes. Static means unmoving, so the term static electricity implies an unmoving static charge. Hope that helps!

@@lovattphysics6366 I appreciate your reply and I understand why and how they call it static electricity but don't you think that it's about time we started to call it for what it is really, to many times I have seen people misunderstand the concept of something all because we have people who should know better keep calling it incorrectly! Static electricity is only one, another misunderstand item is the humble transistor! People who should know better continue to tell people that it's a switch! Even though it can act as a switch, it is not! It's just a potentiometer! The only difference between the two is that one is adjusted mechanically, ie by hand and the transistor is adjusted electrically... They both do exactly the same thing! Albeit... The transistor can ramp up and down much faster than you or I can by hand... Which is why they are also used as a switch... So when people are taught correctly about anything, they will have a better understanding of what it is and what might be possible that hasn't been discovered yet... Education is key! But when you have these people say things like static electricity!!! What are all these people who are new to electronics going to imagine it is... You and I know that a static charge is nothing more than that when a circuit isn't present... In it's most simplistic understanding... But the reality is that even a static charge will dissipate it's energy without a circuit, given enough time... This is also a fact of electronics that need to be understood and factored into you circuit for correct function to be achieved... So essentially a charge that doesn't move is static and a charge that moves is electricity... It's not that hard... But when I see comments from people saying thank you, I now understand! I personally know that they don't! All that they saw was a pulse of electricity which produced the electric spark that came from a build up of a static charge of electrons... I really hope that this helps someone that might have thought differently... Electronics is the future and we need as many people as possible in this field... But not people who don't understand...
