This is the last element in this equation. The resistivity goes right here. So, the bigger the resistivity, the bigger the resistance. That makes sense. And then it also depends on these geometrical factors of length and area. So, here's a formula to determine what factors actually change the resistance of a resistor.

WebA fundamental parameter of the strain gage is its sensitivity to strain, expressed quantitatively as the gage factor (GF). GF is the ratio of the fractional change in electrical resistance to the fractional change in length, or strain: The GF for metallic strain gages is usually around 2.

"WebOhm’s Law. Ohm’s law states that for some devices there is a relationship between electric potential difference, current, and resistance. The equation is: I =\dfrac {\Delta V} {R} I = RΔV. Where I I is current, \Delta V ΔV is electric potential difference, and R R is resistance. " - Derivation of gauge factor from ohm's law

Web5 years ago. Parallel conductance is simply a different viewpoint of parallel resistors. It's the same circuit configuration, but uses a different equation. The "conductance" viewpoint looks at a parallel resistor and instead of seeing a 1/R term in the parallel resistor formula, it sees a G = 1/R term.
