Question

Which of the following statements regarding primary cells is false?

(a) Primary cells cannot be recharged

(b) They have low internal resistance

(c) They have an irreversible chemical reaction

(d) Their initial cost is cheap

This question was addressed to me during an interview.

I'd like to ask this question from Electrochemical Cells in division Electrochemistry of Chemistry – Class 12

Answer 1

Right option is (b) They have low internal resistance

Best explanation: Primary cells cannot be used again and again. Since there is no fluid inside, these cells are also known as dry cells. The internal resistance is high and the chemical reaction is irreversible. Their initial cost is cheap.
