    ESR variation of photoflash capacitors placed in series RLC discharge circuit

    Hi, I plan to design a series RLC discharge circuit as shown: Taking into account component parasitics, the actual circuit resembles the following: where: 'R' = capacitor ESR + load resistance + inductor ESR, 'L' = capacitor ESL + load inductance ≈ load inductance According to online...
