When having a capacitive circuit powered by AC, you get higher resistance as the frequency gets lower and lower. Why does that happen?Also, does the same thing happen in AC circuits with no capacitanc...
As far now, the highest voltage I ever seen a boost converter converting is 90V. What stops a boost converter from generating thousand or million of volts?
Hello, I was about to purchase some heat shrink tubing when I noticed they come in plain as well as a dual wall type that has an adhesive/glue layer. My question is whether anyone has found issues wit...
As it shows, there are two isolated areas of the ground pour. I'm using Eagle, so when I do the pour it does not place in these type of areas unless I explicitly place a via where the bottom...
Hello guys, I need to turn on a small DC motor when a applied reference voltage is removed. Do you know a circuit diagram for this or any idea of doing this?
Why RC oscillators are used for generating below 1MHz frequencies, and LC oscillators for above 1MHz freqs? Why cant we use RC for high freqs, and LC for low-medium freqs?
The ACS712 outputs a voltage from 0-5V and the ESP32 ADC reads from 0 to 3.3V using 1.1V as vref. There is a voltage divider already to reduce the 5V to 3.3 range.The problem is: voltage drops on the ...
