| Keywords: Battery IV curve showing negative static resistance.svg battery showing negative static resistance <font color red > red </font> in its normal operating range The battery is modeled as a voltage source in series with a resistance R<sub>s</sub> representing the battery's internal resistance V<sub>oc</sub> is the battery's open-circuit voltage and I<sub>sc</sub> V<sub>oc</sub>/R<sub>s</sub> is the short-circuit current In its normal operating range the current through the battery is in the direction of increasing electric potential so its static resistance R<sub>static</sub> V/I is negative and it produces power which is consumed in the external circuit Applying a voltage greater than the open circuit voltage or less than zero to it will result in a current in the direction of decreasing potential so the battery consumes power <br /> The battery's static resistance at a given point on its IV curve is equal to the inverse slope of the line from the origin to the point The battery has positive differential resistance equal to its internal resistance 2012-08-19 own Chetvorno cc-zero Uploaded with UploadWizard Negative resistance Device current-voltage characteristics Electric potential | ||||
