The resistance ratio of a and B is 4:5. If a and B are connected in parallel in a circuit, the total power consumed is 18W, then the electric power of a and B is respectively 18W____ W、_____

The resistance ratio of a and B is 4:5. If a and B are connected in parallel in a circuit, the total power consumed is 18W, then the electric power of a and B is respectively 18W____ W、_____

P1=U^2/4k
P2=U^2/5k
P1:P2=5:4
So P1 = 10W
P2=8W
