Why electrolytic capacitors are actually kinda crappy 💩
Electrolytic capacitors are common, but knowledge of their limitations is uncommon. A demonstration is shown highlighting the difference in performance between electrolytic and ceramic capacitors in power supplies. Other topics discussed in the video: Electrolytic capacitor construction, ceramic capacitors, ESR, ESL, impedance curves, why "0.1uF", and more.

    In the thumbnail you can see the diode is directly in the arduino. I would recommend using a breadboard as it does not require any soldering or bending wires.

    True. However I'd like to use N-channel-MOSFETs with their lower RDS-on and cheaper costs. Any idea?

    • @Afrotechmods
      @Afrotechmods 7 дней назад

      You can do it with an N fet on the low side in a similar way just be aware that the resistance you are introducing on the ground path can cause problems in some circuits

    Actually when you break the inductive current, energy starts moving in d-s capacitance of mosfet increasing voltage on it. You can demonstrate it using mosfet with higher current ability and therefore with bigger capacitance or add external capacitor across d-s, the spike becomes less.
