QUESTION: 7

The internationally recommended unit for conductance is

Solution:

The internationally recommended unit for conductance is Siemens (S). 1 siemen = 1 ohm-1

QUESTION: 8

The cell constant G* is calculated by the expression:

Solution:
QUESTION: 9

Which of the following relations are not correct?

Solution:

The correct answer is Option B

k =G*l/A      (Since, G = 1/R)
= l/AR
Therefore, kR = l/A
So, l/A = kR not k/R
