Question

Part A IP The terminals A and B in the figure(Fiqure 1) are connected to a 9.0-V battery. Suppose R1 = 2.9 ' R2 Find the current flowing through each resistor Express your answers using two significant figures separated by commas 8.0 11,12,13,14,15,16 = Figure 1 of 1 Submit My Answers Give Up Part B Is the potential difference across the Re resistor greater than, less than, or the same as the potential difference across the R1 resistor? greater than less than the same as Submit My Answers Give Up

Explanation / Answer

partA] i1 = V/R1 = 9/2.9 = 3.1 A

i2 = V/R2 = 9/4 = 2.2 A

equivalent resistance of R3,R4,R5 = 1/[1/4+1/2.5+1/8.7] = 1.307 ohm

voltage across R3,R4,R5 = 9*1.307/[1.307+8] = 1.264 V

i3 = V345/R3= 1.264/4 = 0.32A

i4 = 1.264/2.5 = 0.51 A

i5 = 1.264/8.7 = 0.15 A

i6 = (V-V345)/R6= (9-1.264)/8 = 0.97 A

partB] less than
