Question

ANALYSIS Use your experimental results to analyze the circuit in terms of Kirchhoff net current fow into and out of each of the four nodes, and determine whetheC s Rules. Consider supported by your data. Determine the net voltage drop around at leaston Sign determine whether or not your data supports the loop rule. (Pay close attosed loops convention.) In adition, verify ir Ohm's law is satisfied for at least three resistors and for the total reji >Q12: Why do you think this circuit is called a "non-trivial" circuit? Did you n eed to Kirchhoff's Rules to analyze this circuit? Can you analyze it using the series/parallet use method? WRAPPING UP > Q13: Under what conditions are Kirchhoff's Rules necessary to analyze a circuit? > Q14: Do you think that the resistance of a voltage probe is large or small? Why? Q15: Do you think that the resistance of a current probe is large or small? Why? > Q16: Can you think of a mechanical analogy to resistance? Explain your analogy.

Answer 1

Kirchhoff's Junction Rule: At any junction in an electric circuit, the sum of currents flowing out that junction. The algebric sum of current in a network of conductor meeting at a point is zero. Sum I_in = Sum I_out Kirchhoff's Loop Rule: - The principle of conservation of energy imply that the directed of energy imply that the directed sum of the electrical potential difference around any closed circuit is zero. Sum_Delta v close loop = 0 R_1 = 51 Ohm R_2 = 33 Ohm R_3 = 27 Ohm R_4 = 68 Ohm R_5 = 10 Ohm r_1 O_1 + R +_2 (I_1 + I_2 + I_3) + R_4 (I_1 + I_3) = 0____(i) R_3 I_2 + R_2 (I_2 + I_3) + R_5 (I_1 + I_2 + I_3) = 0____(ii) v - R_2 (I_2 + I_3) - R_5 (I_1 + I_2 + I_3) - R_4 (I_1 + I_3) = 0____(iii) \r\n Equation-(i) R_1 I_1 + R_5 (I_1 + I_2 + I_3) + R_4 (I_1 + I_3) = 0
