1. Find the power delivered by the 5V Voltage source in the network of Fig.

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....
