    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
