Question 6 Part A Determine the voltage across resistor R2 = 40 2 in the circuit shown in (Figure 1), where us = 60 V, R1 = 20 12 R3 = 30 12, and R4 = 40 12 Express your answer in volts to three significant figures. View Available Hint(s) Learning Goal: To determine the voltage, current, and power of circuit elements using series and parallel equivalents Network analysis is the process of determining the current, voltage, and power for each element, given the circuit diagram and the element values. For some circuits this can be accomplished by reducing the circuit via series and parallel equivalents. A procedure for doing so is outlined below 1. Identify a combination of resistances that are all in parallel or all in series. Redraw the circuit diagram with the equivalent resistance for this combination 2. Repeat step 1 if any reducible combinations remain in your new diagram. 3. Use Kirchoff's voltage and current laws to solve for the voltage and current of the fully simplified, equivalent circuit the results to the second to last circuit and solve for the voltage and current of each element in that circuit. Continue to work backwards until the and current of all the elements in the original circuit are determined. 5. Check your results to verify that Kirchoff's voltage and current laws are satisfied for each loop and node, respectively, and that the powers of all elements sum to zero. Hint 1.
