Section 20.1 Electric Charge and Static Electricity (pages 600–603) This section explains how electric charge is created and how positive and negative charges affect each other. It also discusses the different ways that electric charge can be transferred.
Reading Strategy
(page 600)
Identifying Main Ideas Copy the table on a separate sheet of paper. As you read, write the main ideas. For more information on this Reading Strategy, see the Reading and Study Skills in the Skills and Reference Handbook at the end of your textbook.
An excess or shortage of electrons produces a net electric charge.
Electric Forces
Like charges repel and opposite charges attract.
Electric Fields
The strength of a field depends on the net charge and distance from the charge.
Static Electricity
Charge can be transferred by friction, contact, and induction.

8. A charge’s electric field is the effect the charge has on other charges in the space around it. 9. Circle the letters of the factors that the strength of an electric field depends on. a. the direction of the field b. whether the charge is positive or negative c. the amount of charge that produces the field d. the distance from the charge 10. Is the following sentence true or false? The field of a negative false charge points away from the charge.
Static Electricity and Charging (pages 602–603) behavior of electric charges 11. Static electricity is the study of the . 12. Is the following sentence true or false? Charge can be transferred true by friction, by contact, and by induction. 13. What is the law of conservation of charge? The total charge in an isolated system is constant.
Static Discharge
(page 603)
17. Is the following sentence true or false? Static discharge occurs when a pathway through which charges can move forms true suddenly. 18. How does lightning occur? Negative charge in the lower part of a storm cloud induces a positive charge in the ground below the cloud. Eventually the air becomes charged, forming a pathway for the electrons to travel from the cloud to the ground.

Circle the letter of each sentence that is true about charging. a. When you rub a balloon on your hair, your hair loses electrons and becomes positively charged. b. The sphere of a Van de Graaff generator transfers all of its charge to you when you touch it. c. Induction occurs when charge is transferred without contact between materials. d. Static charges cannot move.
