De spanning tussen X en Y is:
a. 20 V
b. 0 V
c. 10 V
d. 30 V
B+C = 30 Ω
D+E = 30 Ω
BC + DE = 1(1/30 + 1/30) = 15 Ω
A + BCDE = 5 + 15 = 20 Ω
It = U/R = 40/20 = 2 A
Ua =I*A = 2*5 = 10 V
Ubc + Ude = 30 V
Ub = 10 V
Uc = 20 V
Ud = 20 V
Ue = 10 V
X = 40 -10 -10 = 20 V
Y = 40 -10 -20 =10 V >>>>> X-Y = 10 V
