Unformatted text preview: I 1 = 5 6-45 o . + _ 1 Z V oc th I 1 Likewise when we hook up the Thevenin equivalent to the 1F capacitor, the current that fows is I 2 = 10 6-45 o . Two KVL equations can now be written as ollows, or these two circuits: V oc = (1 + Z th ) 5 6-45 o V oc = ( Z th-j ) 10 6-45 o Now we have two equations with two unknowns, V oc and Z th . We can equate the right hand sides o the two equations to eliminate V oc and nd Z th . (1 + Z th ) 5 6-45 o = ( Z th-j ) 10 6-45 o This can be manipulated around to Z th = 2 j + 1 and then we can plug back in to either o those original equations to obtain V oc = 10 2 6 o Problem 3: Part (a) o this problem is Bobrow problem 4.22. Part (b) o this problem is Bobrow problem 4.32. Both o these are very similar to problems you were assigned. The solutions or these two Bobrow problems are in a separate le. 2...
