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.
 
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
