WebCells, EMF and Internal Resistance are inter-related to one another. Batteries i.e. Cells are posses Internal Resistance and potential … WebApr 11, 2006 · Using the current given, you can find an equation relating the emf E and r. But the best way to proceed is to use the following fact: the voltage across the battery is E- Ir and this is the voltage applied to the 5 ohms, E-I r = I R_1. This gives you one equation containing two unknowns: r and E. james the musical gert verhulst
