Angie's Electricity log documents information about electrical circuits and components. A closed circuit allows continuous flow of current through an endless path, while an open circuit is incomplete. Thomas Edison invented the light bulb, which uses wires and gas to light up. Insulators do not allow the flow of electricity, while conductors like metal allow heat, electricity, and sound to travel through. Series circuits have one path for current, while parallel circuits have multiple paths. Static electricity is caused by a buildup of electrical charges, and lightning occurs when positive and negative charges in clouds bump together.
