Explanation / Answer

Ans:-

a] Req

For parallel combination

1/Req = 1/R2 +1/R3+1/R4 =1/25+1/95+1/74

1/Req = 7030+1850+2375/175750

Req1= 15.62

b] 1/Req1 = 1/R2 +1/R3+1/R4

Reqt=( R3*R4 +R2*R4 +R2*R3/R2R3R4 )+R1+R5

c]Reqt = Req1 + R1 +R5 = 15.62 +16+27 =58.62

d]I= /Req

e]I = 8.5/58.62= 0.15A

f] P= I^2R1

g]P= 0.15^2*16 = 0.34w
