An engineering student is attempting to determine the currents through each branch of the circuit in the figure below. The student has assumed the currents are in the directions shown in the figur The student has found that the current I, is 3.77 A and the values of & and R are unknown. 24.0V + a 1+ Is 3.00 03 2 6.00 0 4 What is the magnitude of the current I2 (in A)? 1.22 X Review Kirchhoff's rules. Try applying the loop rule to the right half of the circuit. Review the sign rules for the loop rule and potential differences across circuit elements. Note the question asks for the magnitude of the current. A Does the direction of the current I2 match the direction shown in the figure? Yes, I2 points in the direction shown. No, I2 points opposite to the direction shown. The magnitude of 12 is zero, so there is no direction. What is the magnitude of the current I3 (in A)? Does the direction of the current 13 match the direction shown in the figure? Yes, 13 points in the direction shown. No, I3 points opposite to the direction shown. The magnitude of 13 is zero, so there is no direction. Need Help? Read It
