first we will find equivalent resistance
Req=(R1+R2) parllel to(R3+R4)
=(4+2) parllel to(9+3)
=6 parllrl to 12
1/Req=1/6+1/12
Req=4ohm
Total Current in circuit: Itotal = Vtotal/Rtotal (using Ohms law)
Itotal=8/4
=2amps
Vn=vtotal*Rn/Rtotal
so Vn=8*4/(4+2)
Vn=5.33 V
P=v^2/R
=5.33^2/4
=7.10watt
answer is D
2)Vn=vtotal*Rn/Rtotal
=8*3/12
=2V --answer
