Submit My Answers Give U Part C O 12 is directed to the left O 12 is directed to the right. Submit My Answers Give U

Explanation / Answer

Here ,

let the current in the resistance R1 is I1

current R2 is I2

current R3 is I3

Using KCL

I1 + I2 - I3 = 0

Using KVL

8.4 - 31 * I1 + 35 * I2 =0

again

11.7 + 40 * I3 + 35 * I2 = 0

solving for I1 , I2 , I3

I1 = 0.059 A

I2 = -0.188 A

I3 = -0.123 A

the magnitude of currents is (0.059 A , 0.188 A , 0.123 A)

b)

I1 is directed to the right

c)

I2 is directed to the left

d)
I3 is directed to the upward
