Measure capacitance on a mutual capacitive touch sensor
I interpret the mechanism of a mutual capacitive touch sensor like this:
There are 2 electrodes X and Y. To measure the difference in capacity, the X electrode is driven high (i.e 3.3 V) and the Y ...

Multimeter Negative Resistance
I have a Fluke 87V multimeter and sometimes when I measure some resistors (in power supply PCBs I saw it) it shows me negative value of resistance. Why this? It is some flaw of the multimeter or it ...

Issues with Designed Capacity Measurement Circuit
I made a circuit to determine the capacity of an unknown capacitor. To test if the circuit is working I wanted to test it with a known capacity first. The circuit and the derivation for the ...

Battery capacity evaluation
To measure NiMH battery capacity, everything I've read so far indicates that in order to get an accurate evaluation you have to measure the discharge parameters.
I can understand that, however in my ...

Why does the capacitance value of an MLCC (capacitor) increase after heating?
I have a general purpose MLCC capacitor design kit, which consists of capacitors of different values. I took a 2.2 µF (X5R, 16 V, +/- 20 %, -> this one) capacitor out of it and measured its ...
