RESISTANCE AND EMF OF A BATTERY CELL DCP ASPECT 1 SYMBOLS: Internal resistance of the battery: r External variable resistor: R Voltage: V EMF of the battery: E Current: I FORMULA V= IR E = I (R+r) E = IR +I ⋅ r E = V + I ⋅ r V = E - I ⋅ r V = -r ⋅ I +E _Graph of V against I will be plotted in order to_ _determine the internal resistance and EMF of the battery. The slope will be -r and the intercept vertical axis will be the EMF (E)._ REFERENCE VALUE EMF of the battery 1. 490 ± 0.001V
