Its electriccccc

I would say that electricity is a state or feeling of thrilling excitement, however i don't feel that definition is appropriate for science. Electricity is actually  the flow of electrical power or charge. Electricity is made from from primary sources such as coal and solar energy.Electricity is important because it is a fundamental feature of all matter and we use electricity in everything these days. I would say we need electricity to survive in this day and age. Electric current occurs when an atom becomes charged. Current measures the rate at which electrical charge moves past a point in a circuit. Resistance is the obstruction of electron flow. Resistance is measured in the unit of ohms. Ohm's Law shows the relationship between resistance, current and voltage

kəˈpasitər

A lot of times in Science there are important vocabulary that I never really know how to pronounce or understand what it could mean. One of those words are Capacitor, or a device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator. So what really does this mean? In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. You can easily make a capacitor from two pieces of aluminum foil and a piece of paper. It won't be a particularly good capacitor in terms of its storage capacity, but it will work. Capacitors can be found in my new iPhone 5s, because the capacitors help to translate the sound waves in which we speak into sounds for our ears. Thats a pretty important component if you ask me!
