Specifically it is used for transporting melting pots. With the current, unfortunate installation, the ant...https://electrical.codidact.com/posts/287954What does it mean for a signal to have impedance?Carlhttps://electrical.codidact.com/users/542882023-03-13T19:56:46Z2023-04-05T01:31:40Z<p>What does it mean for signals to have impedance? To me, impedance is kinda like an "extended resistance" that also includes phase shift</p>
$$Z = R + jX $$<p>It makes sense to me that component...https://electrical.codidact.com/posts/286535Unexpected impedance spike when paralleling capacitorsElleanor Lopezhttps://electrical.codidact.com/users/566562022-05-31T08:42:40Z2022-06-02T13:40:19Z<p>I was watching a <a href="https://youtu.be/BcJ6UdDx1vg?t=1611">video</a> from EEVBLOG about bypass capacitors, and he presented a theory that randomly connecting different values of capacitors i...https://electrical.codidact.com/posts/280915Measuring Input/Output Impedance with a VNAjm567https://electrical.codidact.com/users/532992021-02-25T17:10:38Z2021-02-25T21:36:10Z<p>On paper you can measure the input impedance of an amplifier circuit by attaching a voltage source to the input, shorting the output, and calculating the resulting impedance from the voltage and...
