  1. Chapter 6 Capacitors and Inductors

  2. Capacitors A capacitor consists of two conducting plates separated by an insulator (or dielectric). C: capacitance Unit: farad(F) A typical capacitor

  3. Types: fixed variable Polyester Mica Electrolytic Ceramic Values: picofarad (pF) -- microfarad (mF) Circuit symbols for capacitors a) fixed capacitor b) variable capacitor

  4. VAR of Capacitor Passive sign convention A capacitor is an open circuit to dc The voltage on the capacitor cannot change abruptly (in condition that i is limited)

  5. Stored Energy in Capacitor Is capacitor active? equivalent circuit for the parallel capacitors

  6. Equivalent circuit for the series capacitors

  7. Inductors An inductor consists of a coil of conducting wire. L: inductance Unit: henry (H) Typical form of an inductor

  8. Values: microhenrys(H)--- tens of henrys(H) Fixed variable Iron, steel Plastic, air Types: Circuit symbols for inductors

  9. VAR of Inductor What happens when the current is constant? An inductor acts like a short circuit to dc. Integrating form: The current through an inductor cannot change abruptly (in condition that v is limited).

  10. Stored Energy in Inductor Is inductor active? Equivalent circuit for the series inductors

  11. Equivalent circuit for the parallel inductors
