Calculating the power supplied by the current and voltage sources
The power is 6A * 12V = 72W; or the voltage source : you have first to calculate the current flowing in the source, which is the difference between the current in the resistor and the current of the current source. I = 4A - 6A = -2A. And the power is : -2A * 12V = -24W. The minus sign tells the voltage source will RECEIVE 24W

Do batteries (voltage sources) supply constant voltage?
Nick''s answer talks about how the voltage of a battery changes as the battery is discharged, but that is not what defines a voltage source: A voltage source with a knob on it that changes the voltage still is a voltage source, and it still is a voltage source if the knob is hooked up to a clock motor that slowly turns it down over a period of time.

Understanding AC/DC Power Supply | Article | MPS
A power supply is an electrical device that converts the electric current that comes in from a power source, such as the power mains, to the voltage and current values necessary for powering a load, such as a motor or electronic device. The objective of a power supply is to power the load with the proper voltage and current.
Electric Power Sources
That''s because most power sources in the world function similarly to ideal voltage sources. Batteries and generators are both modeled after ideal voltage sources. So remember: when we use the term ''voltage source'', we are talking about a source that tries to supply constant voltage, but will do so imperfectly in real life.
