## Homework Statement

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

## Homework Equations

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

## 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 sense because there would be no generator in the circuit.
