Question
Assume that V = 8.0V and R = 12 Ohm . Find V1 in the figure. (Figure 1) Express your answer to two significant figures and include the appropriate units. Find V2 in the figure. Express your answer to two significant figures and include the appropriate units.Explanation / Answer
20 and 8 are in series so r' = 28ohms then r' and 12 are in parallel =>r'' = (28*12)/40 = 8.4Ohms Then r'', 25, 30 are in series So r_equivalent = 63.4Ohms I = V/r_equivalent = 0.126182965A 8-(25*I) = V1 =>V1 = 8-(25*0.126182965) = 4.845425875V V2 = (8-(25*I)-(30*I)) = (8-(55*I)) = (8-(55*0.126182965)) = 1.059936925V
