Are the potentials of the electrolytes equal in Galvanic cell?
Consider a closed circuit with a resistor connected to a battery,
I have created a graph with each position on the horizontal axis and the electrical scalar potential on the vertical axis.
A graph of ...

Find the total resistance and explain how
This is one of those horrible textbook questions designed to confuse students.
The middle-most resistor is supposed to be rotated. Then you can straighten and align all the other resistors so show a ...

Doubt in Potentiometre Resistance
The circuit you are investigating is shown below and you are going to compare potential differences across the battery, ie across nodes $A$ and $B$, $V_{\rm AB}= \dfrac{\mathcal E \,R}{r+R}$.
The ...

Doubt in Potentiometre Resistance
if we connect an external resistance in parallel to the cell, then why is resistance added like seris while calculating the current flowing through the cell and resistance ?
The confusing aspect (...
