Question

The distance between two electrodes of a cell is 2.5 cm and area of each electrode is 5cm2 .The cell constant is :
OPTION A: 2
OPTION B: 12.5
OPTION C: 7.5
OPTION D: 0.5

Answer 1

The value of the cell constant is 0.5 cm^-1.

Option (d) is correct.

Explanation:

• We are given that:
• Distance between two electrodes = 2.5 cm
• Area of each electrode (A) = 5 cm^2
• As we know that
• The formula is given below to find the cell constant between the electrodes.
• Cell constant (G) = Length / Area

Solution:

Cell constant (G) = I / A

Cell constant (G)  = 2.5 / 5

Cell constant (G)  0.5 cm^-1

Thus the value of the cell constant is 0.5 cm^-1.
