Question

please help with equations 1, 2 and 3. I am confused!

act. - approx 1.1001 act 3) Now let's try it out! Use the provided resistors, wires, and bumseries to create the circuit shown above Measure the equivalent resistance with the multimeter. Then connect the circuito current meter den the battery. Record the current through the battery give a least 2 sificat) View Video and then powse it once you have recorded the current below. Now calculate the percent Ro - 48.29 43.2 -1.87 (measured) Rea 143 = 75.4 4.1007 48.2 -0.0539 A (measured) 0.0539-0.253 error - 75.4 % (resistance) Ich 0.0539 % error - 369 % (current) 41 • 100%. = 3694 Part 2: Kirchhoffs Rules RI 2 For the circuit shown below, the directions of the currents through the circuit elements has been chosen arbitrarily. Using Kirchhoff's rules, you will determine the actual currents through the circuit elements. (Yes, this circuit could be analyzed using equivalent resistance, but don't do it that way) Kirchhoff's Junction Rule 4) Start by choosing a junction. Write Kirchhoff's Junction rule for that junction below as equation 1. Eq 1: Kirchhoff's Voltage Rule for loop rule) w 5) Now before shrinking yourself down you must identify a R3 starting point and a path to walk around the circuit that brings you back to the starting point R4 a) On the figure, label your starting point "A" b) Draw your path (the loop you intend to walk that returns you to your starting point and label it "path A" c) Don't forget to indicate the direction you intend V1 walking around this loop. d) Walk your chosen loop and use the rules for batteries and resistors to determine whether the voltage changes you encounter are positive or negative voltages changes. Write down all voltage rises and drops (adding them up) and set them equal to zero. Do this symbolically, no numbers. This is equation 2 Eq. 2 6) Do this a second time using a different starting point. a) On the figure, label your starting point "B" b) Draw a new path (the loop you intend to walk that returns you to your starting point) and label it "path B". c) Don't forget to indicate the direction you intend walking around this loop. d) Walk your chosen loop and write down all voltage rises and drops (adding them up) and set them equal to zero. Do this symbolically, no numbers. This is your third equation. E4.3:
