Explanation / Answer

R1 = 12 ohm

R2 = 29 ohm

R3 = 85 ohm

V = 5.5 V

part a)

R2 and R3 are in parallel so

Re = R2 * R3 / (R2 + R3)

Re = (29 * 85) / (29+85)

Re = 21.62 ohm

part b)

R1 and Re are in series so

R = R1 + Re

part c)

R = 12 + 21.62

R = 33.62 ohm

part d)

the current on R1 is the total current so

I = V / R

part e)

I = 5.5 / 33.62

I = 0.16 A

part f)

the total potential difference is the sum across R1 and Re so

delta V = (I * R1) + delta V2

delta V2 = delta V - (I*R1)
