1. Ch. 21 - Electricity I. Electric Charge I. Electric Charge (p.592-597)  Static Electricity  Conductors  Insulators  Electroscope

2. A. Static Electricity  Static Electricity  the net accumulation of electric charges on an object  Electric Field  force exerted by an e - on anything that has an electric charge  opposite charges attract  like charges repel

3. A. Static Electricity  Static Discharge  the movement of electrons to relieve a separation in charge

4. B. Conductors  Conductor  material that allows electrons to move through it easily  e - are loosely held  ex: metals like copper and silver

5. C. Insulators  Insulator  material that doesn’t allow electrons to move through it easily  e - are tightly held  ex: plastic, wood, rubber, glass

6. D. Electroscope  Electroscope  instrument that detects the presence of electrical charges  leaves separate when they gain either a + or - charge
