Question 7 This question contains multiple parts. Make sure to read all the instructions and answer each part. The circuit below contains several batteries and resistors. You can assume all batteries are ideal (no internal resistance). Let R1 = 3.06 02, R2 = 11.1 02, and R3 = 3.02 0. R. 10 12 - 5V R, R 2 Part a For this circuit, the currents /1, 12, and Is have been labeled for you. Which equation describes the correct relationship between these three currents? Select the correct answer O h1 + 12 = 13 O In + 13 = 12 O I3 + 12 = 11 No answer submitted Part b Using the counterclockwise direction, which of the following are the consistent voltage loop equations for this circuit using the labeled currents I1, 12, and Is and resistors R1, R2, and Ry 1. IV - (1)(R1) - (1)(R2) - 5V + (12) (10) = 0 2. 1V - (1)(R1) - (1)(R2) + 5V - (12) (10) = 0 3. 4V + (12) (10) + 5V - (13) (R3) = 0 4. 4V - (12) (10) +5V - (13) (R3) = 0 5. 1V - (1) (R1) - (1)(R2) + (13) (R3) - 4V = 0 6. 1V - (1)(R1) - (11)(R2) - (13)(R3) + 4V = 0 Select the correct answer O 1, 4, & 6 O 1,3, & 5 O 2, 3, & 6 O 1,4, & 5 O 2, 4, & 6 O 2, 3, & 5Part c I will help you out by solving for the second current: 12 = (Rat1)( R, +Ra)+Ry . Now you solve for 11. [Hint: The current /1 may be a positive or negative value, be careful to input the correct sign for 1 along with the correct number.] Please enter a numerical answer below.
