Remember
1/Rp = 1/R1 + 1/R2
Rs = R1 + R2
Rp = R1*R2/(R1+R2)
for 8 ohm and 8 ohm in parallel
Rp1 = 8*8/16 = 4 ohm
for 16 ohm and 4 ohm in series
Rs1 = 16 + 4 = 20 ohm
for 10 ohm and 10 ohm in series
Rs2 = 10 + 10 = 20 ohm
for 20 ohm and 20 ohm in parallel
Rp2 = 20*20/40 = 10 ohm
So,
Req = 10 ohm
V = 60 V
I = 60/10 = 6 amp.
Now current will equally distribute between upper and lower 20 ohms
Iup = 3 amp.
Idown = 3 amp
Now I up will be same in both 10 ohm Resistance because they are in series
I(10) = 3 amp.
I(10) = 3 amp.
Now Idown will be same in both 16 ohm and 4 ohm Resistance because they are in series
I(16) = 3 amp.
I(Rp1) = 3 amp.
Now again Current will equally distribute between 8 and 8 ohm
I(8) = 1.5 amp.
I(8) = 1.5 amp.
Now for voltage calculation
V(10) = I(10)*10 = 3*10 = 30 V
V(10) = I(10)*10 = 3*10 = 30 V
V(16) = I(16)*16 = 3*16 = 48 V
V(8) = I(8)*8 = 1.5*8 = 12 V
V(8) = I(8)*8 = 1.5*8 = 12 V
