Dear sir/madam, can you tell me exactly what is the difference between external and internal resistances?
Asked by Harminder Singh | 29th May, 2011, 12:00: AM
The opposition that the cell must overcome internally is called the cells internal resistance.
Look at the following sketch.
And the external resistance is the resistance applied in the circuit and it is applied in series with the internal resistance.
The opposition to the input energy in any system is often called the load. In the above case the load comprises an external resistance R and an internal resistance r. After all, the current must pass through the cell itself as well as through the external circuit.
