In RLC circuits at resonance, the inductive reactance (Xl) equals the capacitive reactance (Xc), and the supply voltage is in phase with the current. At the initial moment, while the current is zero, the voltage across the inductor and capacitor reaches its maximum, indicating energy storage. The problem requires calculating the energy stored in these reactive components using specific formulas. It is important to note that t=0 does not imply the generator was just activated; it reflects a steady state prior to measurement. Understanding these concepts clarifies the energy dynamics in the circuit.
