Weston standard cell at 20°C has voltage of _______ volts
Correct answer: C. 1.0187
- A. 0.8
- B. 0.9
- C. 1.0187
- D. 1.5
Explanation
The Weston standard cell has a reference emf of approximately 1.018 V at 20°C, conventionally stated as 1.0187 V in this type of question. The other values are nominal voltages of common cells rather than the Weston standard.
