The internal resistance of a lead-acid cell is less than that of an Edison cell.
A lead-acid cell is a type of electrochemical cell that uses lead and lead dioxide as electrodes. The electrolyte is sulfuric acid. The cell produces a voltage of about 2 volts.
An Edison cell is a type of electrochemical cell that uses nickel and iron as electrodes. The electrolyte is potassium hydroxide. The cell produces a voltage of about 1.2 volts.
The internal resistance of a cell is the resistance to the flow of current through the cell. The internal resistance of a cell is determined by the materials used in the cell, the size of the cell, and the temperature of the cell.
The internal resistance of a lead-acid cell is less than that of an Edison cell because the lead and lead dioxide electrodes in a lead-acid cell are more conductive than the nickel and iron electrodes in an Edison cell. The electrolyte in a lead-acid cell is also more conductive than the potassium hydroxide electrolyte in an Edison cell.
The internal resistance of a cell is important because it affects the amount of current that can flow through the cell. The higher the internal resistance, the less current that can flow through the cell. This is why lead-acid cells can produce more current than Edison cells.
