The discussion focuses on the impact of resistors R5 and R6 on the output voltage (Vo) and current (ia) in a circuit with parallel resistors. It is established that R5 and R6 do not cancel out but rather do not contribute to the voltage drop due to no current flowing through them. The correct approach involves analyzing the two voltage dividers formed by the remaining resistors to determine the midpoint voltage. The conclusion is that Vo is not 0V, contrary to initial assumptions.
PREREQUISITESElectrical engineering students, circuit designers, and anyone involved in analyzing or designing circuits with parallel resistors.
They don't "cancel out" (weak terminology). There is no current going through them so no voltage drop across them. Better to say that their values are not relevant to the solution of the problem. Vo is not 0V. You have 2 voltage dividers-- evaluate the midpoint voltage of both of them.Cisneros778 said:
