railway RRB JE (CBT I + CBT II) Mock Test 2024 Sensors and Industrial Instrumentation Measurement of PH
The voltage (E0) developed across a glass electrode for pH measurement is related to the temperature (T) by the relation
1
\({E_0} \propto \frac{1}{{{T^2}}}\)
2
\({E_0} \propto \frac{1}{T}\)
3
E0 ∝ T
4
E0 ∝ T2
