Uniform Electric Field

• What is the formula for electric field strength in a uniform field?

  E = V / d
• What does the variable E represent in the electric field strength formula?

  Electric field strength (V m^-1)
• What does the variable V represent in the electric field strength formula?

  Potential difference between the plates (V)
• What does the variable d represent in the electric field strength formula?

  Separation between the plates (m)
• What are the equivalent units for electric field strength?

  V m^-1 and N C^-1
• How does increasing voltage affect electric field strength?

  It increases the electric field strength
• How does increasing separation between plates affect electric field strength?

  It decreases the electric field strength
• Why can't the electric field strength formula be used for point charges?

  Because the field is radial around point charges
• In which direction is the electric field between two charged plates directed?

  From positive plate to negative plate

  
• What is the relationship between electric field strength and potential difference in parallel plates?

  • Electric field strength is the ratio of potential difference to separation.
  • Formula: E = V / d

  
• How do you calculate electric force acting on a point charge between parallel plates?

  Use F = QV / d

  
• What is the work done on a charge moving through a potential difference between parallel plates?

  • Work done (W) is given by:
  • W = Fd
  • W = QV
  • Depends on electric force and distance.

  
• What are the key equations for electric field strength between parallel plates?

  1. E = F / Q
  2. E = V / d
  3. F = QV / d
  4. W = Fd
  5. W = QV
