The rest of the circuit is quite simple: only two capacitors, an inductor, and a resistor are needed. [Valentine] does note that the circuit is quite sensitive, so you might encounter issues when ...

In some ways, the very term “voltage divider” explains itself. It refers to a simple, passive circuit in which multiple resistors are used in order to divide a ...

But there are a number of problems with this simple method ... that keeps the current between the unknown resistor and the rest of the circuit at zero. This prevents current flowing except ...
