1 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley PowerPoint Lectures for College Physics, Eighth Edition Hugh D. Young and Robert M. Geller Lectures by James L. Pazun Chapter 17 Electric Charge and Electric Field

2 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Goals for Chapter 17 To study electric charge, conductors, and insulators. To understand Coulomb’s law and solve some example problems. To understand electric fields. To calculate electrical forces. To map out electric field lines

3 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Exploring the nature of electrical charge - Figure 17.1 Plastic, silk, rubber, glass and fur can reveal fundamental behaviors of charge.

4 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Atom Picture

5 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Atomic charge arrangements – Figures 17.2, 17.3 Protons (+) and electrons (-) account for atomic charges. Electrons move, protons don’t.

6 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Charge movement by conduction – Figure 17.4 Direct contact Charge moves through a conductor. – Metals are good conductors – Non-metals are most often not Discuss insulators. Discuss semiconductors.

7 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Charging by induction – Figure 17.5 If attracted or repelled, the electrons inside an object may be polarized.

8 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Static effects even uncharged objects – Figure 17.6

9 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Polarization (the paper and the comb) – Figure 17.8 Induced charges are present in the everyday examples.

10 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Polarization determines induced charge – Figure 17.7

11 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley How Coulomb measured the force – Figure 17.9 Read through the text on pages

12 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Electrical force – Examples 17.1 and 17.2 Refer to the problem solving strategy on page 554 then try examples 17.1 and The problems build complexity in layers be sure to do these two!

13 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Forces are additive – Example 17.3 Refer to the worked problem on page 556 and figure

14 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Forces are additive even if non-linear – Example 17.3 Refer to the worked problem on page 557 and figure

15 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Mapping out the electrical field – Figures Moving the test charge can allow forces to be measured.

16 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Force causes acceleration – Example 17.5 Refer to the worked problem on page 559 and figure

17 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley Calculating the electric field – Example 17.6 Refer to the worked problem on page 561 and figure

18 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley The field around a dipole – Example 17.7 Refer to the worked problem on pages and figures and

19 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley The electric field is mapped – Figures Refer to the characteristics at the bottom of page 563.

20 Copyright © 2007 Pearson Education, Inc. publishing as Addison-Wesley The field formed related to the electrode – Figure Refer to the text in the middle of page 564.
