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 capacitance using an LCR-Meter. I measured ~1.8 µF at 1 kHz…

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 calculation of the capacity are: I measured the voltages…

What is a volt?

How a volt is measured and defined in the simplest terms? What does it mean when you measure voltage using a voltmeter? In the past, we defined things by physical things. For example, the kilogram was defined by a shiny ball we arbitrarily said was…

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 mind it would be easier and more efficient to…
