л-pad attenuators are commonly used in radio frequency and microwave transmission lines and can be balanced or unbalanced designs. The unbalanced attenuator shown in figure 2 below is supplied by two DC sources, one at each end. You have been asked to calculate the current through R3 and R5 using the Superposition Theorem and the appropriate set of values from table 1 below. Show step by step working out. 5 R1 R2 50V 5 R5 R3 ㅋ Fig 2 7 R4 4 R6 30V
