Question

Which statement best describes a battery?

A) Identical cells are arranged in the same orientation to increase the energy output.
B)Identical cells are arranged in opposite orientations to reverse the half reactions. C)Different cells are arranged in the same orientation to increase the energy output. D)Different cells are arranged in opposite orientations to reverse the half reactions.

Answer 1

im not 100% but i think b

Answer 2

The correct answer is option A.

Step-by-step explanation:

Batteries are connected group of electrochemical cells that stores electrical charges and generate electric current due to conversion of chemical energy into electrical energy.

These electrochemical cells are arranged in a same orientation so as to keep the polarities of the cells in same direction which will provide ease in movement of electrical charges. Preferably these electrochemical cells are identical.
