Calculating Power Supplied by CS and VS Sources

In summary, the power supplied by the voltage source (VS) is 24W and the power supplied by the current source (CS) is -24W. This can be found by using the equation P=Vi, where V is the voltage and i is the current.

The current source is pointed downwards and is 2A while the VS is 12V
They are asking for the power supplied by each source.

Homework Equations


V=ir
KCL
KVL
P=Vi,i^2R,V^2/R

The Attempt at a Solution


I'm not sure how to begin this problem. My initial instincts tells me to simply use P=Vi so that the power supplied by the VS is 24W while the CS is -24W but I'm not sure if this is correct.

Any help would be appreciated, thanks in advance.

Edit: VS in the picture should be on the far right side of the "circuit"

Yes, it's correct.
 

What is the formula for calculating power supplied by a CS source?

The formula for calculating power supplied by a CS source is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps.

What is the formula for calculating power supplied by a VS source?

The formula for calculating power supplied by a VS source is P = I x V, where P is power in watts, I is current in amps, and V is voltage in volts.

What is the difference between a CS source and a VS source?

A CS (constant voltage) source maintains a constant voltage output, while a VS (variable voltage) source allows for varying voltage output based on the load.

How do I calculate the power supplied by both a CS and VS source in a circuit?

To calculate the total power supplied by both a CS and VS source in a circuit, you can add the individual power values calculated for each source using the formulas mentioned above.

Why is it important to accurately calculate the power supplied by CS and VS sources?

Accurately calculating the power supplied by CS and VS sources allows for proper design and functioning of electrical circuits. It also helps in determining the efficiency and potential limitations of a circuit.
