ECE 205 A, B, and C Quiz#3 Name: Calculator Model: 1. Find the equivalent resistance at terminals a-b of circuit in the figure below (10pts). 12 and 60 ohm resistors are in parallel. Hence, 12//60 = 10 ohm. This 10 ohm and 20 ohm are in series to give 30 ohm. This is in parallel with 30 ohm to give 30//30 = 15 ohm. And 25//(15+10) = 12.5. Thus R ab =5+12.5+15=32.5 Possibly useful formulas R R R R R R R R R R arallel: stors in p For N resi eries: stors in s For N resi v KVL i at KCL iR v N eq
