We suppose that the voltage U at the input end is constant.
We suppose that the load is star-connected with insulated null.
We'll consider as an origin of time the passage from K¢₁ ON to K₁ ON.

• Which is the evolution of the current i¢ from 0 to T if we are in a steady state regime?

• What is the value of the current i when we are in a steady state regime?
• Which is the frequency of this current?
