Energy in Resonant Circuits: Consider how the energy flows around different components of a circuit at resonance. General Role of Circuit Components: In general, where is energy input into the circuit? Where is energy taken out of the circuit? Where is energy stored in the circuit? Analyzing Power through Components: To see how the energy flows between different components, we should understand what the power is through various components at different times. Consider a resonant circuit with (for simplicity) L=R=C=V0=1...
