Back EMF in DC Shunt Generator Formulas

Back EMF is developed when current flows through the armature, it generates a magnetic field that interacts with the field produced by the field winding to produce a torque. And is denoted by E_b. Back EMF is usually measured using the Volt for Electric Potential. Note that the value of Back EMF is always negative.
