Current Electricity is the rate at which charges pass a given point. The higher the current is the greater the number of charges pass the point each second. Current Electricity works by tiny invisible things called electrons that move through metal. The electrons move in a wire, make up a current and provide energy to the things we use each day. Electric circuits go through a path were current electricity flows. Circuits can be every where such as lights, a clock, and a computer. It can even connect to more then one room or have more than one load. We need Current Electricity because we use things in our everyday life that have Current Electricity, from computers and hairdryers to lamps and washing machines.

Static Electricity is the electric charge at rest on an object. When something is static it is not moving. The charges of static electricity do not move away from the object because they are in, so the object keeps its charge. Static Electricity works by when the electrical charges inside an atom, made up of an equal amount of protons, electrons and neutrons become unbalanced. It is also often caused when the various portions of electrical charges present in particles separate. When two particles with similar charges get next to each other, they move away. This sometimes causes a spark otherwise referred to as a static discharge. Static Electricity is important to understand because there can be a danger of static such as lightning. Lightning usually strikes the highest point In a charged area because the point provides the shortest path for the charges to reach the ground. Anything that strikes up or out in an areas are at risk of being struck by lightning.

The dangers of current and static electricity is minimum. But the dangers of current electricity is Static electricity is usually a 'high voltage' but low power form of electricity. Lightning is static electricity, and it can damage buildings and harm people. Dangers of Electricity include a variety of hazards that include Electric Shock, Psychological Damage, Physical Burns, Neurological Damage and Ventricular fibrillation resulting in death. Any form of energy, when not properly controlled or harnessed, can result in serious danger to those who use it. The risks inherent with electric power can generally be divided into two categories: direct and indirect. The direct danger is the damage that the power itself can do to the human body, such as stoppage of breathing or regular heartbeats, or burns. The indirect dangers of electricity include the damages that can result to the human body as a result of something caused by electric shock, such as a fall, an explosion, or a fire. Electricity at any voltage can be dangerous and should always be approached with caution. An electric shock can occur upon contact of a human or animal body with any source of voltage high enough to cause sufficient current flow through the muscles or nerves.

Safety procedures for static electricity is avoid A point of great danger from a static spark like where a flammable vapor is present in the air, such as the outlet of a flammable liquid fill pipe, at a delivery hose nozzle, near an open flammable liquid container, and around a tank truck fill opening. Safety Procedures for current electricity is Current flows through you and other conductors, such as metals, earth and concrete. Current can harm you when it flows through your body (electric shock). Insulators resist the flow of electricity. Insulating materials are used to coat copper conducting wires and are used to make electrical work gloves. Insulators help to protect humans from coming into contact with electricity flowing through conductors. Just as there is pressure in a water pipe, even with no water flowing, there is voltage at a receptacle, even if current is not flowing. Another word for voltage is "Potential."

One safety rule for current electricity is When possible, try to avoid working in carpeted areas. Carpeting greatly increases static buildup within your body. One safety rule for current electricity is the area in which you're working should be free of water and other liquids. Keep cords, tools and even yourself dry when working with electricity.
