1. Answer the subparts A&B with the step, based on the Image. This question Q&A please no reject and solve thank u A) Based on the measurement data above, indicate that there is an error in the measurement      data. Give an explanation of the answers given. B) Determine in which element there is an error in the measurement data. What should be       the correct measurement result. Give an explanation of the answers given.

Suppose the three branch currents in this circuit are I₁ = -3 A, I₂ = -18 A, and I3 = -15 A. The voltage drop across each circuit element is as given in the table below. From this information, determine, for each of these circuit elements, (i) whether an active or passive sign convention is being used for that element, (ii) whether that element is absorbing or producing a net (positive) amount of electrical power. In each answer box within the table below, type the correct choice from among the bold-faced words above. V₂ B A B A C D 1₁ A B 1₂ 1₂ + Circuit element Voltage drop Sign convention? Absorbing or producing net electrical power? -9 V -2 V C 9 V -11 V D

Question 3 (a) Briefly explain what is the per-unit systero. (b) A resistance of 60n is selected as the base resistance in a circuit consists of three resistors. If R, =1002, R, =30002 and %3D R, = 200 calculate the per-unit vahue of each resistance. %3D (c) A power of, P-25KW and a voltage of, E-2400V are selected as the base power and base voltage of a power system respectively. Calculate the value of the base impedance, Z, and the base current, I,. (d) A resistor bas a per-nnit value of 5.3. Given the base power is P=250KW, and the base voltage is E,-12470V, calculate the ohmic value (actual value) of the resistor. (e) A 4000 resistor caries a cucrent of 60A. Given the base valne of voltage, E, 4KV, the base value of power, P, 500KTF, the base value of current, I, =125.4, and the base value of resistor, 2, = 320 calculate the following: i The per-unit resistance. ii. The per-unit current. ii. The per-unit voltage across the resistor. iv. The per-unit power.

4. Consider the following circuit. 3R SR 2R a) How many distinct currents flow in this circuit? The four loops shown are labeled A - D, and the junctions are labeled a - d. b) If we had to solve for these currents, how many independent equations would we need? c) Which loops and/or junctions would you choose, if you had to solve for the currents? (Many answers are possible here.) This diagram shows several different loops and junctions in the circuit. d) Set up a system of equations that would allow you to solve for the currents.
