Step-by-step explanation:

Ohm's law applies: V = IR, and variations. The current in a series circuit is the same through every element. That current is given as 1.1 A.

Rt = (8 V)/I3 = (8 V)/(1.1 A) = 80/11 Ω = 7 3/11 Ω

R3 = Rt -R1 -R2 = 7 3/11 -2 -5 = 3/11 Ω

It = I3 = 1.1 A

I1 = I2 = I3 = 1.1 A

V1 = (I1)(R1) = (1.1 A)(2 Ω) = 2.2 V

V2 = (I2)(R2) = (1.1 A)(5 Ω) = 5.5 V

V3 = (I3)(R3) = (1.1 A)(7/11 Ω) = 0.3 V
