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?
