Question

The objective of this problem is to find Vac in the network in the figure. The numerical solution is Vac = 3.00 V. You must show your work to get credit. In which direction will current flow in this circuit, clockwise or counterclockwise? Explain your reasoning. Annotate the schematic with the voltage source current and the current in each resistor. How are these related? Annotate the schematic with the voltage across each resistor. Annotate the schematic with Vac. The subscript notation (Vac) means that the voltage is annotated with the + at node a and the - at node c. How is Vac related to the resistor voltages? Hint: use KVL to find the relationship. Use Kirchhoff's Voltage Law and Ohm's Law to solve for the resistor voltages and Vac.

Explanation / Answer

Req = 10+20+30 = 60 kohm so, I = V/R = 6/60 = 0.11mA So, Vac = Iac *Rac = 0.1*30 =3V
