I had been googling on this topic
so DC produces no harmonics. Thus there is no need for a Hall sensor.For harmonic measurements, which device is suitable?
Hi,
When we talk about frequencies or frequency analysis (like with Fourier analysis): DC means 0 Hz, no fluctuation.
When "your DC" fluctuates, then this is caused by AC.

I would be okay calling DC current as a current that has some net average one way current flow.
Multiple frequencies can coexist...and DC, too. No problem with this.Turning on a DC device changes current so DC device that draws current must not exist.
Surely not. Because the very very most of the energy is drawn by the DC component. And the AC ripple is not much of interest. But it does exist.A DC to AC sinewave power inverter has a fullwave rectified sinewave battery current profile so it should be called an AC to AC inverter by your definition.
No, you would not. The output of an audio amplifier will have some "average one way current flow", almost unavoidable.I would be okay calling DC current as a current that has some net average one way current flow.
Related to current sensors, the important point is if you want to measure this "net average one way current flow", simply can ignore it or need to assure that it doesn't disturb the AC component measurement.I would be okay calling DC current as a current that has some net average one way current flow.
If you consider "net average one way current flow" over a complete period (cycles) then the AC component automatically gets canceled.Related to current sensors, the important point is if you want to measure this "net average one way current flow", simply can ignore it or need to assure that it doesn't disturb the AC component measurement.
