Which of the following primary cells has the lowest voltage_________ ?
Correct answer: C. Mercury
- A. Lithium
- B. Zinc-chloride
- C. Mercury
- D. Carbon-zinc
Explanation
A mercury cell has a nominal voltage of about 1.35 V, lower than the roughly 1.5 V of zinc-chloride and carbon-zinc cells. Lithium cells generally provide a higher voltage, so mercury is the lowest here.
