Question
All of these questions correspond to each other so I couldnt send them seperately, Thank you!
Using the equations found in the previous problem, solve for the magnitudes of currents I_1, and I_2, and I_3. You should also record these theoretical values in the appropriate space in the Data and Analysis portion of your lab report. Attach a separate piece of paper if you need more room. Suppose that the 680 ohm resistor in problem 0 was replaced with a resistor of infinite resistance. Would I_1 increase, decrease, or stay the same? A. increase B. decrease C. stay the same How would I_1 and I_3 compare? A. I_1 would be greater than I_3 B. I_1 would be less than I_3 C. they would be equal.Explanation / Answer
from junction law
I1 + I2 + I3 = 0 .......(1)
for left loop
12 - I1*470 + I2*680 + 9 = 0 .......(2)
for right loop
-9 - I2*680 + I3*1000 = 0.............(3)
solving 1 , 2, 3
I1 = 0.02 A
I2 = -0.003 A
I3 = -0.017 A
---------------------
infinite resistance is connected (I2 = 0)
I1 = 12/(470+1000)
I1 = 0.008 A
decrease
OPTION(B)
====================
I1 = I3
OPTION (C)
