Hello!
I've got two exercises:
1. Draw every time function (voltage across any element and current in any circuit element) which might possibly appear in first-order circuit i.e. in a circuit with one and only one capacitor or inductor and an undefined number (possibly large) of resistors and constant sources (both voltage and current) switched at t=0.
2. Assume a simple serial RL circuit with a real inductor (i.e. with internal resistance R_L). How can you calculate R_L from the voltage U_L(t)? Give appropriate expression.
It is my solution:

However, I don't know how to sketch graph of Uc (first exercise) and calculate internal resistance of coil (second exercise). How to take into account many sources (especially I don't know what to do with ideal current sources) or resistors (first exercise)? Can you help me, please?
Greetings!
