Electric Fields Types of Charges Methods of Charging Conductors and Insulators Concept of an Electric Field Uniform Electric Field

Electrical Charge Proton Electron Positively charged Charge = + 1.60 x 10-19 C Mass = 1.67 x 10-27 kg Electron Negatively charged Charge = - 1.60 x 10-19 C Mass = 9.11 x 10-31 kg

Methods of Charging Charging by Friction

Triboelectric Series

Methods of Charging Charging by Induction

Methods of Charging Charging by Conduction

Materials Conductors Insulators Materials that allow electricity to flow Examples: Metals Insulators Materials that inhibit the flow of electricity Examples: Plastic and Rubber Materials

Like charges repel; opposite charges attract. Repulsive forces Attractive forces

How can charges exert forces on each other when they are not even in contact with each other?

Concept of the Electric Field Region of space where a charged particle can experience a force

Concept of the Electric Field

Electric Field Force per unit positive charge E = F/q Units: NC-1
