A 20 foot length of two-conductor 26 AWG copper wire is used to connect a single strain gage into a quarter-bridge circuit. If each conductor has a resistance of 20.4 Ω per 1000 feet, how much has the apparent gage resistance changed? Calculate the strain induced by this error if the initial gage resistance is 120 Ω and 350 Ω.
