Study Notes

LC Circuit Characteristics

  • In an LC circuit, the charge on the capacitor and the current on the inductor vary sinusoidally with time.

Induced EMF

  • The magnitude of the induced emf can be calculated:
    • If the average value of Bcosθ decreases from 0.54 T to 0.0032 T in 0.13 s.
    • If there are 127 loops in the coil, the induced emf will be:
      • A. 7.11 V,
      • B. 3.94 V,
      • C. 17.78 V,
      • or D. 148.59 V

Types of Electric Fields

  • Electrostatic electric field:
    • A type of electric field
    • Differentiated from non-electrostatic/induced electric field
  • Non-electrostatic/induced electric field:
    • A type of electric field
    • Differentiated from electrostatic electric field
    • Occurs when there's a change in the magnetic flux

Faraday's Law

  • Used to determine the induced emf in some physics problems
  • The emf is proportional to the number of turns in a coil
