(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate the power in the voltage source for this given circuit:

2. Relevant equations

[tex]P = \frac{V^2}{R}[/tex] Or [tex]P = - \frac{V^2}{R}[/tex]

3. The attempt at a solution

If we take the bottom left corner as the Initial node then and go around the circuit, then the voltage is a drop thus I thought we use: [tex]P = \frac{V^2}{R} = 10W[/tex] however this means power is positive hence the voltage source is also an absorber which wouldn't make sence because there would be no generator in the circuit.
