## 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

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