Phasor Representation: Vrms/Irms or Vmax/Imax?

AI Thread Summary
In phasor representation for AC voltages and currents, it is acceptable to use either Vrms and Irms or Vmax and Imax, as long as consistency is maintained. Mixing the two types of magnitudes can lead to confusion and incorrect calculations. The key point is to ensure that both voltage and current are expressed in the same form, either RMS or peak values. Understanding the context of the application can help in choosing which representation to use. Consistency in phasor analysis is crucial for accurate results.

Guys,
Quick one, When you do phasors for AC voltages and current... is it theVrms and Irms or can it be Vmax and Imax..? I mean the magnitude of them...I am bit confused

thanks guys, got the answer it does not matter of which one you take the phasor of as long as you don't mix them up...
 

Thread 'What happens if shielded cable has short to the shield?'

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...

Thread 'Underwater piezoelectric sensor array receive sensitivity'

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...

Thread 'Question about bonding ground and neutral'

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...
