Explanation / Answer

part a)

for the parallel resistance ,

1/Req = 1/R2 + 1/R3 + 1/R4

Req = R2 * R3 * R4/(R2 * R4 + R3 * R4 + R2 * R3)

b) for the total resistance

Rtotal = R1 + R5 + R2* R3*R4/(R2*R4 + R3*R4 + R2*R3)

the total resistance is R1 + R5 + R2* R3*R4/(R2*R4 + R3*R4 + R2*R3)

c)

R = 19 + 27 + 75 * 54 * 84/(75 * 54 + 84 * 75 + 54 * 84)

R= 68.9 Ohm

d)
using Ohm's law

current passing through R1 = /R

part e)

current passing through R1 = 9.5/68.9 A

current passing through R1 = 0.138 A
