DC Circuit Components provides a comprehensive overview of the different parts that appear in DC circuits, including source, path, control, and load. DC power sources include batteries, generators, ...

The circuit in Figure 2 meets these requirements and accurately measures internal resistance over a range of 0.001 to 1Ω at battery voltages as high as 13V. One section of an LTC6943 analog switch, IC ...

The circuit shown in the figure can monitor resistance in a noisy or otherwise hostile environment. A 1:1 transformer provides isolation and a good common-mode rejection ratio (CMRR).
