Assume a single-phase AC voltage applied to a series circuit with a certain impedance. Because of the real and imaginary part of the impedance, we get both real and reactive power. Now, if we were to connect a capacitor in parallel with the circuit, and if this capacitor supplies a certain...
Hello, i am trying to understand the concept of active /reactive /complex power and am having some trouble understanding how the reactive powere 'oscillates back and forth between inductor and source'.
Ok, let's say i have a pure inductive load, i know that the power consumed is 0, and i...
Hi,
Can someone please explain to me how you can get higher RMS voltage ratings across components than the supply voltage and how VAR ratings can become huge?
Indeed what really is reactive power? I've been introduced to it for years but have never fully understood it and I could do with...
My professor made this statement: "the power dissipated by an inductor will always be purely reactive and represented at 90 degrees" (we label real power as a phasor at 0 degrees, inductive reactive power at 90 degrees and capacitive at -90)
Why is this?
I made a little example with a...
