What are the factors on which internal resistance of cell depends?
Thus, the internal resistance of a cell depends on the factors like distance between the electrodes, the temperature, the effective area of the electrodes and the concentration of the solution.
Does internal resistance of cell depends on the current draw from the cell?
No. Internal resistance of a cell doesnt depend on the current drawn from it. Hello, Internal Resistance does not depends upon the current because it is simply the amount of opposition offered to the flow of electric current by the elecrolyte of the cell.
What is internal resistance of cell?
Internal resistance refers to the opposition to the flow of current offered by the cells and batteries themselves resulting in the generation of heat. Internal resistance is measured in Ohms. Example: 1 The potential difference across the cell when no current flows through the circuit is 3 V.
Does internal resistance depend on temperature?
In the presence of electrolyte, internal resistance, Ri is inversely proportional to temperature T. It is because, as we increase the temperature, more electrolyte dissociates and resistance decreases.
Why internal resistance is inversely proportional to the area?
Internal resistance of a cell depends on the concentration of ions moving in the electrolyte and as the cross sectional area of the electrode is increased more number of conducting ions will be taken up by the electrode from the electrolytic solution due to which there will be an decreased traffic in the movement of …
How does the distance between electrodes affect internal resistance?
The internal resistance of a cell is directly proportional to the separation between the electrodes. The internal resistance of a cell is inversely proportional to the area of the electrodes dipped in electrolyte. The internal resistance of a cell is inversely proportional to the concentration of the electrolyte.
