Explanation / Answer

Here ,

a) for the current i2

the resistance on the left of battery

Req = (R2 * R1)/(R1 + R2) + (R3 * R4/(R3 + R4))

Req = 16 * 16/(16 + 16) + 7 * 7/(7 + 7)

Req = 11.5 Ohm

current i2 = E/Req

current i2 = 31.5/11.5 A

current i2 = 2.739 A

b)

for the circuit in the right

Req = R7 + R5 * R6/(R5 + R6)

Req = 4.7 + 3.2 * 7/(3.2 + 7)

Req = 6.87 Ohm

current i4 = E/Req

current i4 = 31.5/6.87 A

current i4 = 4.57 A

c)

current i1 = i2 + i4

current i1 = 4.57 + 2.739

current i1 = 7.307 A

d)

Using current divider for current through i3

current through i3 = i2 * R4/(R3 + R4)

current through i3 = 2.739 * 7/(7 + 7)

current through i3 = 1.37 A
