2. Force-sensing resistor - Wikipedia

   en.wikipedia.org/wiki/Force-Sensing_Resistor

   A force-sensing resistor operating based on percolation exhibits a positive coefficient of pressure, and therefore, an increment in the applied pressure causes an increment in the electrical resistance, [12] [13] For a given applied stress , the electrical resistivity of the conductive polymer can be computed from: [14]

3. Ohm's law - Wikipedia

   en.wikipedia.org/wiki/Ohm's_law

   Similarly, the rate of flow of electrical charge, that is, the electric current, through an electrical resistor is proportional to the difference in voltage measured across the resistor. More generally, the hydraulic head may be taken as the analog of voltage, and Ohm's law is then analogous to Darcy's law which relates hydraulic head to the ...

4. Electrical resistance and conductance - Wikipedia

   Also called chordal or DC resistance This corresponds to the usual definition of resistance; the voltage divided by the current R s t a t i c = V I. {\displaystyle R_{\mathrm {static} }={V \over I}.} It is the slope of the line (chord) from the origin through the point on the curve. Static resistance determines the power dissipation in an electrical component. Points on the current–voltage ...
