In the circuit shown on the left, $R_2=3$ and $R_3=2.$ The current flowing through $R_2$ is from point $c$ to point $f,$ and the potential difference across $R_2(V_{R_2})$ is $18V.$ The current over $R_3$ flows frd point $d$ to point $e$ and the power dissipated by $R_3(P_{R_3})$ is $8$Watt. What is the direction and value of current flowing through $R_6?$

A$.$ Trem poirt a no point b$,2,A$

$8.$ Irom point b to poinca B:A

c$.$ From point a to point b$/4A$

D fram point b le point cill A

E$.$ Tromprom o to paint $B$ iA
