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. WebMicroscopically, Ohm's law is a statement about how application of an electric field to a conducting material leads to an electric current: \vec {J} = \sigma \vec {E}. J = σE. In the above equation, \sigma σ is a constant … 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. howee top 100
