10.1 Electrostatics with Conductors

    Cards (24)

    • Electrostatics is the study of electric charges at rest
    • Electric shielding is the ability of a conductor to block external electric fields
    • Steps of charge distribution on a conductor in an electric field:
      1️⃣ Free electrons redistribute themselves
      2️⃣ Electric field inside becomes zero
      3️⃣ Charge accumulates on the surface
      4️⃣ Surface charge density increases at points of greater curvature
    • What is an example of a practical application of electric shielding?
      Faraday cage
    • A conductor allows electric charges to move freely through it.

      True
    • Match the concept with its description:
      Charge Distribution ↔️ Redistribution of free electrons on a conductor's surface
      Surface Charge Density ↔️ Charge per unit area on the conductor's surface
    • Electric shielding blocks external electric fields by using a conductor
    • Electric cables transmit electrical power efficiently with minimal loss
    • What happens to free electrons when a conductor is placed in an electric field?
      They redistribute themselves
    • What is the primary focus of electrostatics?
      Electric charges at rest
    • What does the surface charge density on a conductor's surface represent?
      Charge per unit area
    • What is electrostatics the study of?
      Electric charges at rest
    • What happens to free electrons in a conductor when placed in an electric field?
      They redistribute themselves
    • What is the electric field inside a conductor in electrostatic equilibrium?
      Zero
    • What is a Faraday cage used for?
      To protect electronic equipment
    • Match the application with its description:
      Electric Cables ↔️ Transmit electrical power efficiently
      Faraday Cages ↔️ Shield electronics from EMI
    • The electric field inside a conductor in electrostatic equilibrium is always zero.
      True
    • A conductor allows electric charges, specifically free electrons, to move freely through it.
    • Inside a conductor in electrostatic equilibrium, the electric field is zero because free electrons produce a field that cancels out any external field.
      True
    • In a conductor, electric charges are not bound to individual atoms
    • The surface charge density on a conductor is denoted by the symbol \sigma
    • The electric field inside a conductor is zero because free electrons cancel out the external field.

      True
    • Electric shielding involves redistributing free electrons to cancel external fields.

      True
    • What does grounding in electrostatics prevent?
      Electrical shocks
