hey everybody!...sorry for the stupid question...Can you use Thevenin, Norton, superposition and Node analisys in RLC circuits?...if so...could you pass some examples circuits?...Thanks!
 
Engineering news on Phys.org
for example...i have this circuit i got from Industrial Electronics by Timothy Millman...can the components values be calculated using Nodal Analysis, or thevenin, or supersposition?... would it be??...what if i assume RL as a DC motor? (has some inductance and resistance)...so technically the circuit would have RLC components...

You might pay attention to the fact that the ECG 5414 is a SCR.
But, barring max current limitations of the SCR the RLC characteristics of the motor are not important to the circuit operation.
