The circuit shown is connected to an ideal voltage source with an EMF = AVb. Each of the resistances is given as a number times a standard resistance R: R1=X1R, R2=X2R, R3=X3R What is the voltage drop over R3? Let: x1 = 7, x2 = 4, x3 = 5, AVb = 18.4V Give your answer in Volts to at least three signicant digits. Grade Scope Solution: Your Grade Scope solution should show your work and give an equation for AVg, the voltage drop across R3, in terms of ONLY the variables x1, x2, X3, and AVb. You may not need to use all these variables in your answer. (Note: This does NOT include R.) Your Grade Scope solution should NOT INCLUDE THE NUMBERS given above
