Haemocytometer
Haemocytometer is used to count the blood cells. It has a glass microscope slide that has a central chamber that has a grid. It is done by preparing the sample, then loading it in the hemocytometer. Then counting of the cells are done under a microscope and then the concentration of the cells are calculated.
So, the correct answer is (A): Haemocytometer
A quantity \( X \) is given by: \[ X = \frac{\epsilon_0 L \Delta V}{\Delta t} \] where:
- \( \epsilon_0 \) is the permittivity of free space,
- \( L \) is the length,
- \( \Delta V \) is the potential difference,
- \( \Delta t \) is the time interval.
The dimension of \( X \) is the same as that of:
