Web12 sep. 2024 · Using Kirchhoff’s loop rule to analyze the circuit as the capacitor discharges results in the equation − VR − VC = 0, which simplifies to IR + q C = 0. Using the definition of current dq dtR = − q C and integrating the loop equation yields an equation for the charge on the capacitor as a function of time: q(t) = Qe − t / τ. Web11 apr. 2024 · Another modeling approach that could be considered is a Kirchhoff migration . Kirchhoff is ray-based, and although it may not capture the mode-conversion and scattering of wave-equation-based methods, it could result in fewer migration artifacts, which are highly present, given the non-ideal geometry of the vibe points, and the fiber in …
