electricity chapter 10

• electrons and their movements
• used to power homes and everything else

• electricity that isn't in a circuit
• lightning is an example
• charging by friction, contact and induction

• the use of friction to change the charges on two objects by rubbing them together
• higher electrostatic=higher pull on electrons

a list of items in the order in which they hold onto electrons

• a material that doesn't conduct electricity well
• opposite of conductor

• a material that conducts electricity well
• opposite of insulator

• something that is ok at conducting electricity
• eg. silicon
• useful for electronics

• an object that neutralizes other objects
• eg. the ground!

• a device used for measuring charge
• metal leaf and pith ball

• touching two objects with different charges together
• equilibrium created, both objects gain mild charge

• same charges repel
• different charges attract
• neutral loves everyone

when electrons move around in an object because another charged object is in the vicinity

• a charged atom
• kinda simple

• rod used to stop electrocution of buildings
• usually large
• conducts electricity to ground

• used to catch dust particles through charges
• especially in factories and chimneys of large buildings

• creates charges through friction
• used to accelerate particles
• really awesome!

• a device for measuring radiation by detecting charges
• helpful for people who get radiation exposure
