In the two-loop circuit shown, V1=12 V, V2=18 V, R1=2, , R2=15, , and R3=10, . (The battery V2 has its positive terminal at the bottom.) Use nodal analysis to find the voltage at node a (the top of R2) with respect to the bottom wire.
- 6.3 V
- -3 V
- 10.59 V
- 12 V
Answer
A. 6.3 V
Solution
Node a: Va-V1/R1+Va/R2+ Va-(-18 V)R3=0. Solving gives Va=6.3 V.
