<i> = 0 dans certaine situation
ieff = rcin(<i²>)
i² = E²/R²
P = UI = RI²
i = E/R (graph)
ik1 = ik2
ig = ik1+ik2
sens courant = diode ou inter
positif/néga => passage par diode ou inter
Va0 = E/2 quand K1
-E/2 quand K4
Uab = Va0 - Vb0 = Van - Vbn
Ubc = ?
Uca = ?
Van = (Uab - Uca)/3
'a' sur extremité
Uab - Uca = ?
Van + Vbn + Vcn = 0 (équilibré)
Efficace de U
U = Racine(2/3)*E
Efficace tension simple
V = (Racine(2)/3) *E
