Study route
27.1 Free fluctuations in LC
- The charged capacitor is discharged through the coil: electrical energy is turned into magnetic energy, then the process goes back.
27.2 Switch current
The current is equal to a constant current that produces the same average power in the resistor.
27.3 Transformer
The variable flux in the heart creates the EDS in the secondary winding. The stress ratio is approximately equal to the number of turns.
