Question

Problem 21.63 Figure 1 of 1 previous 12 of 15 ne Part A IP Find the current in each resistor in the figure(Eigure 1). Suppose the four resistors in this circuit have the values R1 3.3 2, R2 5.7 n R3 2.7 n, and R4 9,9 n, and that the emf of the batteries are E1 12 V and E2 9.0 V Express your answers using two significant figures separated by commas. 11, 12, 13, 14 0.61,0.87, 1.5.0.61 A Submit My Answers Give Up Correct Part B ls the potential at point Agreater than, less than, or equal to the potential at point B? greater than less than equal to My Answers Give Up Correct Part C As 3.87 current flows from A to B A" has more "B". Current always flows from higher potential to lower potential so, VA

Explanation / Answer

Ans)

From part A

Currents I1=0.61A

I2=0.87A

I3=1.5A

I4=0.61A

Given that R1=3.3

R2=5.7

R3=2.7

R4=9.9

For partD

Potential difference between the points A and B is

VA-VB=I3R3

=1.5x2.7

=4.05 V
