Marx Generator Stage & Energy Calculator
For the classic Marx circuit — proposed by Erwin Otto Marx in 1923 — the theoretical impulse output is N × VC and the total stored energy is ½ × Cstage × VC² × N. Useful for sizing checks and configuration validation.

Vout = N × VC | E = ½ × Cstage × VC² × N | Ceq = Cstage / N
Real-world output is lower than ideal due to spark-gap losses, stray capacitance, wave-shaping resistors and load capacitance. Treat this as an upper bound used for first-pass sizing.
