1. Find the power delivered by the 5V Voltage source in the network of Fig.
This is my attept at solution:
At node 1 V1...assuming current leaving V1:
KCL equation: -1A+1A+[(V1-5)/3]+[(V1-(V2-10))/2]=0
At node 2 V2...assuming current leaving V2:
KCL equation: -2A-1A+[V2-(V1+10)]=0
But, I'm not certain about the sign convention when there is a voltage source with a resistor between V1 and V2....
I'm also confused that how to proceed when there is a current source and resistor between two nodes.....
Where did I go wrong...?
Please help me....
