</matlabcentral/answers/uploaded_files/23934/rlc.PNG> Data to calculate:

Build the system of ordinary differential equations for voltage on capacitor and current on inductance as state variables. Solve the system of equations using Adams-Bashfort-Moulton of the 4th order algorithm. Plot the current and voltage distributions on ALL elements on separate plots. Calculate the power disspating on each element during a period of time T. (Use Simpson’s 38 rule). Calculate the temperature of each electrical element in steady state using the given termal resistances and formula: Rth=ΔT/ΔP, where ΔT=T−Ta is the temperature between the element and the environment Ta, ΔP is the power disspating on the element. Assume that the surrounding environment has a constant temperature Ta=250oC.
