Question

The values of the currents $I_1$, $I_2$, and $I_3$ flowing through the circuit given below is

• A. $I_1 = -3$ A, $I_2 = 2$ A, $I_3 = -1$ A
• B. $I_1 = 2$ A, $I_2 = -3$ A, $I_3 = -1$ A
• C. $I_1 = 3$ A, $I_2 = -1$ A, $I_3 = -2$ A
• D. $I_1 = 1$ A, $I_2 = -3$ A, $I_3 = -2$ A
• E. $I_1 = 2$ A, $I_2 = -1$ A, $I_3 = -3$ A

Hint:

Always assign current directions first. Negative results indicate actual direction is opposite to assumed.
