1. The problem statement, all variables and given/known data im trying to find the characteristic equation of a circuit with a current source and 3 elements all in parallel: a resistor and 2 inductors L1 and L2. 2. Relevant equations i believe the current can be calculated as: i(t) = v(t)/R + iL1(t) + iL2(t) 3. The attempt at a solution is this anywhere close? (1/R)dv/dt + 1/L1(v) + 1/L2(v) = 0 i guess i don't understand what is equated in a characteristic equation.
