All of these questions correspond to one another, so I couldnt send them seperately

When the switch is closed in the circuit shown, currents I_1, I_2, and I_3 will flow in the segments with the 470 ohm. 680 ohm, and 1000 ohm resistors, respectively. Using the current directions, loop directions, and junction indicated in the diagram, write three independent equations that can be used to solve for currents I_1, I_2, and I_3. Using the equations found in the previous problem, solve for the magnitudes of currents I_1, 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 1 was replaced with a wire of zero 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? I_1 would be greater than I_3 I_1 would be less than I_3 they would be equal.

Explanation / Answer

1)

i1 current from battery

i1 = 12 / Req

Req = 874.76 ohm

i1 = 0.0137 A

i2 = i1 680/1680 = 0.00555A

i3 = 8.1654 A

3)

increases

4)

i1 would be greater than i3
