    Ac Switch
Click For Summary
The discussion focuses on setting up a two-way switch in PSPICE to alternate between the outputs of a capacitor and an inductor connected in parallel. Users are advised to utilize the sw_tclose or sw_topen switches from the evaluation library for this purpose. Monitoring both outputs simultaneously can provide insights into how the inductor's reactance increases with frequency, while the capacitor's reactance decreases. Observing phase changes with frequency adjustments is also suggested, although resonance effects may be missed without specific configurations. Properly connecting the components can help in analyzing the resonance when reactances are equal.

Hello People!

So currently I have an AC input going into a capacitor and inductor in parallel, and I want the output from the capacitor and inductor to go into a switch that flips from outputting the capacitive load's output and the inductor's load output, a little diagram is shown below:

Instead of two resistors, both outputs would go into a switch with the switch's output connected to a load resistor. How could I go about making this switch and checking it in PSPICE? Thank you in advance!

switch in pspice called sw_tclose or sw_topen (N.o_Or N.C switch), both can be found in eval library

edit: the emoji stands for normally open, I can fix it but I find that amusing

You could just monitor two outputs at the same time with a Spice program.

You would see that the inductor increases its reactance with rising frequency, so you would get less output. And the capacitor has the opposite effect.

You could observe the changes in phase that occur if you change the frequency.

However, you would miss the resonance effect that occurs when the reactances of the capacitor and inductor are equal.

For this, you could connect both the inductor and capacitor together at one end of a resistor which is connected to ground at the other end.
 
Thread 'I thought it was only Amazon that sold unsafe junk'
I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
