Contact UsEnergy stored in a LC circuit
The energy stored in a LC circuit is directly proportional to the oscillation frequency. This means that the more energy that is stored, the higher the frequency of the oscillations will be. This can be seen in the formula for calculating the oscillation frequency, f = 1 / (2 * π * √(LC)), where L is the inductance and C is the capacitance.
