UC Berkeley, EECS Department B. E. Boser EECS 40 HW4: Source Transformations UID: 1. For evaluation, circuit (a’) is temporarily connected to circuit (a) and the following measurements are taken with the ampère- and volt-meters shown in circuit (a’) (for different values of R L ): i) V = V A = mA ii) V = V A = mA a) Determine the values of V T and R T such that circuits (a) and (b) behave identically. V T = 1 pt. 0 R T = 1 pt. 1 b) The apprentice is asked to verify the measurement, but inadvertently mixes up the volt- and ampère- meters. What readings does he get when redoing measurement (i) above? Use the values from part (a) for V T and R T . V = 1 pt. 2 A = 1 pt. 3 2. Find component values such that all three circuits shown behave identically. Given:
