Voltage divider - Wikipedia

In electronics, a voltage divider (also known as a potential divider) is a passive linear circuit that produces an output voltage (V out) that is a fraction of its input voltage (V in). Voltage division is the result of distributing the input voltage among the components of the divider. A simple example of a voltage divider is two resistors connected in series, with the input voltage applied

Current divider - Wikipedia

Current divider. A general formula for the current I X in a resistor R X that is in parallel with a combination of other resistors of total resistance R T is (see Figure 1): = + where I T is the total current entering the combined network of R X in parallel with R T.Notice that when R T is composed of a parallel combination of resistors, say R 1, R 2, etc., then the reciprocal of each

N5ESE's Classic RF Probe

The RF Probe is one of the handiest accessories you can have around the shack. Using only 3 electronic components, it may rank as one of the simplest and cheapest homebrew projects.
