For the life of me, I couldn't answer it..
Anyone help me out?

rollcast said:I forget now how it works (I'm sure some one can correct me) if you where to use constant current then the frequency would vary with load which would mean certain devices such as synchro motors wouldn't spin at a predictable speed.
berkeman said:If you used an AC current source, why would varying the frequency change the power output (to adjust to the load)? I'm not understanding what you are saying...
I'm sure you mean V = I x R.berkeman said:The current drawn from the voltage source is dependent on the resistance of the load, according to Ohm's Law:
V = V x R
berkeman said:Or
I = V/R
Constant current sources have their applications in electronics, but not in power distribution. You use voltage sources for power distribution.
EDIT -- Just to add a bit more... Common power sources like batteries and electric generators are voltage sources, not current sources.

Electrical outlets in a home serve as a source of power for various electronic devices and appliances. They are designed to provide a safe and convenient way to connect electrical cords and plugs to the home's electrical system.
The number of electrical outlets in a room depends on the size and purpose of the room. As a general rule, there should be at least one outlet every 12 feet along the walls. Rooms such as kitchens and living rooms may require more outlets to accommodate multiple appliances and electronics.
Yes, it is possible to add more electrical outlets to a home. However, this should always be done by a licensed electrician to ensure the safety and proper installation of the outlets. Adding outlets may also require upgrading the home's electrical system to handle the additional load.
The third prong on an outlet is called a ground pin and is a safety feature. It connects to the ground wire in the home's electrical system and helps to protect against electric shock in the event of a short circuit or other electrical issue.
If an outlet is not working, the first step is to check the circuit breaker or fuse box to see if the circuit has been tripped or the fuse has blown. If that is not the issue, then the outlet may need to be replaced or repaired by a professional electrician. It is important to never attempt to fix an electrical outlet yourself as it can be dangerous.
