180 is the answer amount of ohms needed on the oscilliscope. I need to transpose the equation to solve for R. I must work out an equation that equals 180 ohms R resistance that gives off 50mA of current using the transposed equation. Series impedence ,inductive reactive, phase angle formulas may need to be used. I need to get as close to 180 ohms as possible.

A lead wire and an iron wire are connected in parallel. Their respective specific resistances are in the ratio 49: 24. The former carries 80 percent more current than the latter and the latter is 47 percent longer than the former. Determine the ratio of their cross sectional areas ROUND OFF TO THE NEAREST HUNDRETHS

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.

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
