Assume that the increase and decrease in the resistance of the strain gage element is by the same number of ‚ñ≥R. Determine the unbalanced voltage equation?# |
| A. | V = – V<sub>dc</sub>×(△R/R) |
| B. | V = – V<sub>dc</sub>×(△R/R+△R) |
| C. | V = V<sub>dc</sub>√ó(‚ñ≥R/R) |
| D. | V = – V<sub>dc</sub>×[(△R+ R)/R]. |
| Answer» B. V = ‚Äö√Ñ√∂‚àö√ë‚àö¬® V<sub>dc</sub>‚Äö√†√∂‚àö‚â•(‚Äö√Ñ√∂‚àö¬±‚Äö√¢‚Ä¢R/R+‚Äö√Ñ√∂‚àö¬±‚Äö√¢‚Ä¢R) | |
