We suppose that the voltage 
at the entry is constant. We'll consider as time origin, the moment when 
passes from 
to 
.
- Which is the expression of the current i¢ between 0 à T/2, then between T/2 à T in steady state regime?
- Which is the time constant with which the current i¢ tends towards its steady state regime?
- What is the value of the i current passing through the U source in steady state regime?
