A strain gauge of 120 \( \Omega \) and gauge factor 2 undergoes a strain of 0.001. The change of resistance is
Answer: C
From \( \Delta R = R \times G \times \epsilon \) the change is \( 120 \times 2 \times 0.001 = 0.24\ \Omega \). A fifth of one per cent on a hundred and twenty ohms is why a bridge and an amplifier are needed to see it at all.
