If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

A quick calculation: To estimate a battery’s internal resistance, you can use a simple voltage-drop method when the ...

We often run into the situation where there are two capacitors, one of them charged up to some voltage level and the other at some lower voltage level which, for purposes of this discussion, we will ...
