If a circuit has 5 loops, how many junction rules (current equations would we have?
1. Kirchoff’s Rules are defined in terms of loops and junctions. How would you define a “loop” in a circuit? What is a junction? 2. What happens to the reading of the ammeter if you reverse the connections? The voltmeter? 3. Recall that current is just the motion of electric charges. The Junction rule is a practical manifestation of what more fundamental conservation law? What conservation law implies the loop rule? 4. Write a junction equation for the point B1...
126 S. Consider the large circuit shown in Figure 3, where the components have the following values: We will use Kirchhoff's rules to calculate the current passing through each of the nineteen circuit components. ineteen components in this circuit, there are only twelve through two components that are in series. After considering this fact, draw twelve arrows on Figure 3, indicating twelve distinct currents. Label these currents as 112 These twelve currents are unknown, and we wish to find their...

Theory: Junction rule: Loop rule: Procedure: 1. Consider the following circuit: Ri 11 a. Write down one junction rule equation for this circuit. 1.+13=I b. Write down loop rule equations for the two interior loops (not the perimeter loop). RI+RI=V -V2 -R-I+R;13= V2 c. Solve the equations for 11, 12, and 13. Once you have your equations, show them to your instructor for approval before continuing to the rest of the lab.

You have a current of 5 A flowingin a circuit with an inductance of 2 H. How quickly would you have to reduce the current to 0 A to induce an Emf of 1000 V? Assume the change is constant. If your circuit were an air-filled solenoid with a volume of 10 cm3, how many turns per unit length would there be?
Imagine that we have two solenoids. Solenoid 1 has Nį loops, a length li, and a radius ai, while solenoid 2 has N2 loops, a length l2, and a radius a2. Assume that l2 <lı and a2 > a1. The solenoids are arranged as shown (here we just show the cross-section in the page, but both consist of full, circular loops). For parts a-d, treat the solenoids as ideal. a.

those are my equations, need help on part C c. Solve the equations for l s, la, and ls. Once you have your equations, show them to your instructor for approval before continuing to the rest of the lab. Build the circuit and set V1 = 5.00 V and V,-100V-Be careful to make sure your leads in and out of the power supplies are correct! Do not turn on the power supplies yet 2. Using the values for resistance and...
