Power

AI Thread Summary

Reactive power is the power that is stored and released by electric or magnetic fields in an AC system, while apparent power is the combination of both real power and reactive power, representing the total power in the circuit. Apparent power is measured in volt-amperes (VA) and is crucial for understanding the overall power flow in electrical systems. The confusion often arises because reactive power does not perform any useful work, but is essential for maintaining voltage levels. The discussion highlights the importance of distinguishing between these two types of power for better comprehension of electrical systems. Understanding these concepts is vital for effective power management in electrical engineering.

Hi

I'm kinda confused with the difference between reactive and apparent power. In my understanding, reactive power is basically the power absorbed by either electric or magnetic fields that is later returned to the source. So what is exactly is apparent power?

thanks

I was just about to post I figured it out, sorry for the pointless thread.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
