1.In the step response of parallel RLC circiuts sometimes they ask us to find the voltage as a function of time across the inductor can we first find the current across it and then use the identity v(t)= L di\dt because i think we can not find the initial or final voltage across the inductor ?
2.A trapezoidal channel lined with d50 = 10 cm has a bottom width of b = 1.2 m, side slopes of m = 3, and a longitudinal bottom slope of S0 = 0.008. Determine the normal depth and the Froude number for Q = 1.4 m3/s.
