Which of the following statement about viscosity is not true? it
depends on areas of the surfaces in contact

Correct answer is A
No explanation has been provided for this answer.
E = E\(_1\) + E\(_2\)
E = \(\frac{E_1}{E_2}\)
\(\frac{1}{E} = \frac{1}{E_1} + \frac{1}{E_2}\)
E = E\(_1\) = E\(_2\)
Correct answer is C
If two cells of equal emf s are connected in parallel then the effective emf is equal to the emf of any one of the cells.
