Determine characteristics of capacitance.

Determination should include

  • defining
    • capacitor
    • dielectric
    • dielectric constant
    • microfarad
    • nanofarad
    • picofarad
    • working voltage

  • describing the construction of capacitors
  • drawing the schematic symbols for
    • fixed capacitors
    • variable capacitors
    • polarized electrolytic capacitors

  • explaining the significance of voltage rating and capacitance rating of capacitors
  • calculating parallel capacitance, using the formula CT = C1 + C2 + C3 ... Cn
  • calculating series capacitance, using the formula 1/CT= 1/C1 +1/C2 + 1/C3+...1/Cn
  • listing and explaining the safety factors involved in handling capacitors.

Process/Skill Questions:

  • What are the characteristics of a good dielectric?
  • What are two ways to increase capacitance?
  • Why are most capacitors measured in microfarads and picofarads?
