Determine the voltage vo between nodes A and B in Figure P2.67.
vS = 12V
R1 = 11 k? R3 = 6.8k?
R2 = 220 k? R4 = 0.22M?
Find:
The voltage between nodes A and B.
Analysis:
The same current flows through R1 and R3. Therefore, they are connected in series. Similarly, R2 and R4 are connected in series.
SPECIFY THE ASSUMED POLARITY OF THE VOLTAGE BETWEEN NODES A AND B. THIS WILL HAVE TO BE A GUESS AT THIS POINT.
Specify the polarities of the voltage across R3 and R4 which will be determined using voltage division. The actual polarities are not difficult to determine. Do so.
The voltage is negative indicating that the polarity of is opposite of that specified.
A solution is not complete unless the assumed positive direction of a current or assumed positive polarity of a voltage IS SPECIFIED ON THE CIRCUIT.
