More about Capacitors (74)

1-07-2022 | What do capacitors have in common with wires in water or fingers touching metallic surfaces? Quite a lot, as the author discovered with his...

1-07-2022 | Looking for an analog ESR meter to check and find bad capacitors? You can build your own. Here is one approach. 

23-06-2022 | Capacitive touch interfaces really took hold after their success in the Apple iPod with its rotary wheel. Since then, touch buttons have mad...

19-05-2022 | What do capacitors have in common with wires in water or fingers touching metallic surfaces? Quite a lot. You can use skin impedance for a v...

16-11-2021 | The proposed measurement principle is based on constant current, making the measurement completely insensitive to the series resistance. Th...

7-09-2021 | A bad capacitor shows different capacitance values for charging and discharging; a perfect capacitor will have the same values. Knowing this...

1-07-2021 | In the previous instalment [1] we saw how capacitors block DC but allow AC to pass through. But that most certainly isn't the end of it – vo...

16-06-2021 | A capacity meter is more useful than you might expect.

8-06-2021 | Now that I am at it, might as well add this function too. Sounds familiar? This is such a project. It measures frequency, period and duty cy...

1-05-2021 | After the resistors that we discussed in the previous episode [1], it is now the capacitors' turn. Capacitors also can be considered resisto...
