Question

Determine the magnitudes of the currents through Ri and R2 in the figure (Figure 1), now assuming that each battery has an internal resistance r = 2.6 Express your answer using two significant figures. Enter your answers numerically separated by a comma. ? Figure 1 of1 11, 12 = V,-9.0 V Ri = 22 Submit My Answers Give Up Part B R2 = 15 Determine the directions of the currents through R1 and R2 O 11 to the left; 12 to the left. 11 to the left: /2 to the right I1 to the right; 12 to the right I1 to the right, 12 to the left V3 = 6.0 V

Explanation / Answer

Considering given formula,

A = V1/R1 + V2/R2 + V3/R3

A = -9/(22+2.6) + 0/15 + 6/2.6

A = 1.94

B = 1/R1 + 1/R2 +1/R3

B = 1/24.6 + 1/15 + 1/2.6

B = 0.49

Vparallel = A/B = 3.96 V

I1 = (9+ 3.96)/24.6 = 0.53 A (left)

I2 = 3.96/15 = 0.26 A (left)
