Why Current & Voltage Don’t Match in an LCR Circuit?

Quite possibly the most stupid animation on electrical reactance I’ve seen. For a starter, the capacitance blocks DC.

except that voltage does not “flow’ in an electric circuit. This animation doesn’t even begin to explain.

LCR Commentary: “DC switch closes → capacitor: ‘I’ll charge, thanks’ → inductor: ‘Hold my beer, I’m lagging’ → steady state: ‘lol both of you are blocked, no AC, no party.’”

Badly flawed. Voltage (E) doesn't flow, it's measured potential. The E measured at inductors trails current (I) in time (90 degrees of a cycle) because of the charge time of a radiative magnetic field temporarily storing potential. Across a capacitor, measured E leads measured I.

There are so many things wrongs with this it's difficult to know where to start.

A major and fundamental misconception: electrons don't move; they only oscillate, leading to propagation.

It's wrong interpretation of LCR circuit

But this is a DC circuit, the capacitor will block DC! If you are discussing phase lag, then this is not the appropriate illustration! And Dumbeldor is smarter than Gandalf the gray…

A battery isn't going to cause the effect you were looking for. Instead of a battery you need an AC source to see it.

How is an lcr circuit relevant in case of static dc voltage. So long there is no switching DC, inductor is not going to work at all and capacitor will block dc and final result is no electricity flowing through the circuit. So no lag lead situation.

I have used LCR circuits in AC transmission lines. They use thick copper wires with internal inductance and capacitance generating unwanted reactive power that must be reduced.

But they run negative to positive. Lacking Electrical Knowledge?

We just ignoring that power flows not from Positive to Negative but Negative to Positive? - just letting people be dumb about how power flows? o.O

Stop posting such wrong crap, you will confuse people who start learning physics or electronics. This is a very bad and wrong analogy for this circuit. If anyone is looking for some beginners explanation, check out this explanation instead for example.

An inductor is more like an flywheel not a ramp

This is an animation, not a simulation as a response of the physical laws involved. Electric → Magnetic behavior must be considered.

This is a nice illustration that “mismatch” doesn’t imply error. In reactive systems, phase lag reflects stored energy and system memory — the output depends on state, not just instantaneous input.

I did like the illustration of voltage leading current in the inductor. The illustration fell apart across the capacitor.
