I´m trying to measure the total inductance of a pulsed plasma thruster. According to usual formulas found on books I calculated it should be about 200 nH (very small). The strange thing is that I measured a smaller value than this (about 130 nH). To measure inductance I put a known capacitor in the circuit (so the circuit will be one capacitor and three inductance in series, without generators) and inducted high frequency signal with a toroid, analysing then the spectrum to find the resonance frequency of the circuit and then find the inductance. Is there something wrong in this? Did anyone do something like that? Why I find a smaller inductance than the one evaluated theoretically?

Thanks
