This type of potentiometer has two terminal contacts between which a uniform resistance is placed in a semi-circular pattern. The device also has a middle terminal which is connected to the resistance through a sliding contact attached with a rotary knob. By rotating the knob one can move the ...
total resistance v: voltage \(\begin{array}{l}r=\frac{\rho l}{a}\end{array} \) \(\begin{array}{l}v=i\frac{\rho l}{a}\end{array} \) where, ⍴: resistivity a: cross-sectional area with ⍴ and a constant, i is constant too for a rheostat. \(\begin{array}{l}\frac{...
So, equation (4) is the Formula for Internal Resistance In Potentiometer. To Determine the Internal Resistance of a Given Primary Cell Using a Potentiometer Experiment The aim of our experiment is To Determine The Internal Resistance Of A Given Primary Cell Using A Potentiometer ...
