Homework Statement



Determine the magnitudes and directions of the currents through R1 and R2 in Fig. 19-47, where R1 = 37 and R2 = 16 .

Figure 19-47
(image attached)

V1 = 9.0 V
V3 = 6.0 V
R1 = 37 [tex]\Omega[/tex]
R2 = 16 [tex]\Omega[/tex]

Homework Equations



V = IR

The Attempt at a Solution



V = IR
6.0 V = (37[tex]\Omega[/tex]) I
.16216 A = I [tex]_{}1[/tex](correct)

V = IR
6.0 = (16[tex]\Omega[/tex]) I
.375 A = I[tex]_{}2[/tex] (incorrect)

That's weird, I would say I1 is incorrect and I2 is correct. Did you get the 16Ω and 37Ω values reversed perhaps?

Kirchof's Voltage Law (KVL) would be useful here.
