    OK so there are 2 main types of particles protons and electrons, well there are neutrons and positrons and few otheres but we will only consider these 2.

    Electrons have negative charge and protons have positive charge. This doesn’t indicate anything significant other than they are opposite. Only reason protons are positively charged are is because protons were first discovered by some dude who fired some x ray into a good film with magnets around it. And electrons were discovered later so they got negative charge

    Those electrons are much lighter than protons and they are attracted towards protons so they move in from negative voltage (high concentration of electrons) to positive voltage this can be explained if we consider that protons create a field which attracts electrons. This is electric field.

    So current is just kind of energy that travels with this Field. There are few more rules that this electric field follows which we have found like the electric field inside a conductor is zero I.e all the electricity you see around you is at the very edge of the wire through which it is travelling.

    Then there was that old chap named Maxwell whose laws are followed by all electrically charged particles and you can derive all other laws and equations if you know his 4 equations. I don’t remember them now because I’m too dumb and idiot you can google them. Or better yet duckduckgo them.
