Question

Use the worked example above to help you solve this problem. Find the currents in the circuit as shown in the figure below by using Kirchhoff's rules. R = 5.4 Ohm. 0.444 times I3 Your response differs from the correct answer by more than 10%. Double check your calculations. = A 0.444 times I2 Your response differs from the correct answer by more than 10%. Double check your calculations. = A I1 0.813 A = Use the values from PRACTICE IT to help you work this exercise. Suppose the 6.0-V battery is replaced by a battery of unknown emf, and an ammeter measures I1 = 1.6 A. Find the other two currents and the emf of the battery. I2 = (No Response) A I3 = (NO Response) A epsilon = (No Response) V

Explanation / Answer

applying kirchoff's laws:-

6 - 4*i1 - 9*i3 = 0

-5.4*i2 + 9*i3 = 0

i1 = i2 + i3

solving,

i2 = 0.5085 A

i3 = 0.3051 A

next question:-

E - 4*i1 - 9*i3 = 0

-5.4*i2 + 9*i3 = 0

i1 = i2 + i3
i1 = 1.6

solving,

i2 = 1

i3 = 0.6

E = 11.8
