Chapter 17: Electric Charge and Electric Field © 2016 Pearson Education, Inc.

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. © 2016 Pearson Education, Inc.

Electrical Charges are All Around Us © 2016 Pearson Education, Inc.

Exploring the Nature of Electrical Charge − Figure 17.1 Plastic, silk, rubber, glass and fur can reveal fundamental behaviors of charge. © 2016 Pearson Education, Inc.

Atomic Charge Arrangements – Figures 17.2 and 17.3 Protons (+) and electrons (−) account for atomic charges. Electrons move; protons don't. © 2016 Pearson Education, Inc.

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. © 2016 Pearson Education, Inc.

Charging by Induction – Figure 17.5 If attracted or repelled, the electrons inside an object may be polarized. © 2016 Pearson Education, Inc.

Static Affects Even Uncharged Objects –Figure 17.6 © 2016 Pearson Education, Inc.

Polarization (the Paper and the Comb) –Figure 17.8 Induced charges are present in the everyday examples. © 2016 Pearson Education, Inc.

Polarization Determines Induced Charge –Figure 17.7 © 2016 Pearson Education, Inc.

How Coulomb Measured the Force – Figure 17.9 Read through the text on pages 531 to 537. © 2016 Pearson Education, Inc.

Electrical Force – Examples 17.1 and 17.2 Refer to Problem Solving Strategy on page 534 then try Examples 17.1 and 17.2. The problems build complexity in layers, so be sure to do these two! © 2016 Pearson Education, Inc.

Forces are Additive – Example 17.3 Refer to Example 17.3 on page 536 and Figure 17.11. © 2016 Pearson Education, Inc.

Forces are Additive Even if Non-Linear –Example 17.3 Refer to the Example 17.4 on page 537 and Figure 17.13. © 2016 Pearson Education, Inc.

Mapping out the Electrical Field – Figures 17.15 and 17.16 Moving the test charge can allow forces to be measured. © 2016 Pearson Education, Inc.

Force Causes Acceleration – Example 17.5 Refer to Example 17.5 on page 539 and Figure 17.17. © 2016 Pearson Education, Inc.

Calculating the Electric Field – Example 17.6 Refer to Example 17.6 on page 541 and Figure 17.19. © 2016 Pearson Education, Inc.

The Field Around a Dipole – Example 17.7 Refer to Example 17.7 on pages 542−543 and Figures 17.20 and 17.21. © 2016 Pearson Education, Inc.

The Electric Field is Mapped – Figures 17.23 and 17.24 Refer to the characteristics at the bottom of page 543. © 2016 Pearson Education, Inc.

The Field Formed Related to the Electrode – Figure 17.25 Refer to the text in the middle of page 544. © 2016 Pearson Education, Inc.
