Question

Suppose the series resistors in the example are now 2.00 ? and 1.00 ? while the parallel resistors are 4.00 ? (top) and 2.00 ? (bottom), and the battery provides an emf of 24.0 V.

LEARN MORE REMARKS As a final check, note that AVbc = (6.0 )11 = (3.0 )12 = 6,0 V and Vab = (12 )11 = 36 V; therefore, Vac-Vab + Vbc-42 V, as expected.

Explanation / Answer

here
R' = 2 + 1 = 3
R'' = 4*2/(4+2) = 1.33 ohms

Req = 3 + 1.33 = 4.33 Ohms

From Ohms law we ahve :
I = V/Req
I = 24 / 4.33
I = 5.54 A

By KVl :
3I + 4T1 = 24
3*5.54 + 4I1 = 24
I1 = (24-16.62)/4
I1 = 1.845 A

also

3I + 2T1 = 24
3*5.54 + I1 = 24
I1 = (24-16.62)/2
I1 = 3.69 A
