Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt (one joule per second). Use this tag where power is a primary concern for the design under discussion. Use the "low-power" tag when that applies.

Calculate the average power dissipation in Joules
The only thing I didn't understand is this solution is how to calculate the average power dissipation. It's never mentioned in class and I can't find any formula even to proceed. … And I don't think it is helpful anyway since it gives the average power in Watts.
So, how can I calculate the average power dissipation? …

How did I calculate the power for this source?
Let the circuit be:
Given that Ix = 5A and Vy = 10V, calculate the power absorbed or delivered by each source.
My solution:
10A source delivers 100W (P=UI= (-10 + 20)x10 = 10 x 10 = 100W). …

Why does this current source absorb but not deliver power?
It should deliver and not absorb power.
This seems like double-standard to me. … Why did the solution say the source is absorbing power and not delivering power? …
