Electricity So Far

Physics homework for 2/12/15:

Current Progress

         Electricity is a form of energy that results from the existence of charged particles and/or resulting from a current. So far I learned electricity can come from various places, but always needs some kind of a turbine/generator for it to be used right. Different types of currents like alternate and direct currents can flow to power items like light bulbs so long as there is a generator, for example. I have also learned that you need charged particles for current and that there are various ways to charge atoms (induction, friction, etc.) Additionally, electrons are important in generating electricity currents as they provide the negative charge, heat, and energy to power items up. Plus, the materials that are used to conduct electricity like metal or rubber are important and essentially you want to utilize conductors for electricity purposes. Electricity is important because of how major and significant of a power source it is. It powers the very laptop I use to complete my homework on, it generates energy for my lights, it takes care of the city's power, etc. Humans are VERY reliant on it too, and with out it we would all definitely have some trouble! I'm still confused about mainly how to charge objects, but I am fair at that. I have grasped the concept much more, but I think there might be a few things confusing me. If I remember, I will probably add it here but for now I think it's just charging. And as for today's lab, I guess only the types of currents were confusing but only because I heard the concepts once. I'm getting better at how electrons work and about charging too even though it may still confuse me a bit. Also getting better at understanding how particles work. I have a question about electricity, is it a renewable resource? Is it easy to obtain and generate? And how do batteries work to help with electricity?
