Presentation Transcript

  1. Chapter 21 Current and Direct Current Circuits (+Alternating Current)

  2. A.C. Versus D.C

  3. Study Note No need to memorize any equations in this file. This is just a qualitative introduction to alternating current (a.c.).

  4. Alternating Current

  5. Voltage and Current US: 120V rms, 60Hz Europe: 230V rms, 50Hz

  6. Transformer

  7. Reducing current during transmission

  8. Saving energy, why?

  9. Resistive AC circuit

  10. Capacitive AC circuit

  11. Inductive AC circuit

  12. RLC

  13. Resonance Happens when driving frequency equals natural frequency
