What are the difference between absorbing and delivering power?

What are the difference between absorbing and delivering power?

If a load element or a load subcircuit operates at an I-V point in the upper-right or lower-left quadrants, it is absorbing power. If it operates in the upper-left or lower-right quadrants, it is delivering power.

Do voltage source delivers power?

Ideal voltage sources can be connected together in parallel only if they are of the same voltage value. Note also that voltage sources are capable of both delivering or absorbing power.

Can a voltage source dissipate power?

An ideal example is where current traveling through a resistor causes a voltage drop to occur across its terminals. The voltage drop is indicative of a loss in energy, as voltage is the change in potential energy as charge is moved between two points. It dissipates power when it is being charged.

When does a voltage source not absorb power?

If a voltage source is the only voltage (or current) source in the circuit, and if the other circuit elements are all passive, then the voltage source would not absorb any power. But if there is another source (voltage or current) in the circuit, then, depending on its magnitude and polarity, the first voltage source might indeed absorb power.

Why does this current source absorb but deliver?

VCCS absorbs 192 W. This doesn’t make sense. The current flows in the same direction as VCCS (0.8 Vab). It should deliver and not absorb power. But it does make sense since the source is absorbing power. According to the solution, the voltage across the VCCS is 12V with the top terminal more positive.

How to determine the current across each source?

Question (Extracted from a book): Determine the voltage across each current source, the current through each voltage source, and the power delivered or absorbed by each source.

Can a voltage source provide a positive current?

Its not an appropriate way to think about it. An ideal voltage source can provide current at a fixed voltage, where teh current is positive from the positive terminal. This is considered sourceing current.
