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
