Coulter principle. Ans- The ability to count and measure the size of particles using an electric circuit. Particles are moved through a small aperture, their presence causes a narrowing of the aperture, which leads to an increase in resistance.By using constant I, According to Ohms law (U= I * R), when R increases, U increases and pulse is generated. Parts and functions of the Coulter-counter Ans- - Two spaces with a small aperture in between, capillary (contains the electrolyte sol...
