Presentation Transcript

  1. Electroscopes and Charges

  2. Copper Rubber Charge Distribution • One of these isolated charged spheres is copper and the other is rubber. The diagram below depicts the distribution of - charge over the surface of two spheres. Which one is rubber and which one is copper?

  3. Charge by Conduction • Electrons flow from a charged object to an uncharged object through contact.

  4. Charging an electroscope by contact - What will happen as a positively charged rod is brought near?

  5. Grounding a positively charged electroscope - Which way will the electrons flow?

  6. Charge by Induction of an Electroscope

  7. Charge by Induction • Electrons flow from one sphere to the other due to separation of charge.

  8. Key Ideas • Objects become charged by losing or gaining electrons. • Negatively charged objects have an excess of electrons. • Positively charged objects have a deficiency of electrons. • Like charges repel. • Unlike charges attract. • Conductors allow electrons to flow freely. • Insulators do not allow electrons to flow easily. • Separation of charge occurs when objects become charged or when a charged object is brought in local proximity to an uncharged (neutral) object.

  9. Key Ideas • Charge by conduction results when charge is transferred through contact. • Charge by induction occurs when a charged object is place in local proximity to a neutral object causing a separation of charge.
