Shunt power loss
WebThe Overall efficiency given Armature Resistance formula is defined as the ratio of the mechanical output to the electrical input. Overall efficiency looks at entire systems from the initial input to the final output and is represented as η o = 1-((I-I sh)^2* R a + P loss)/(V s * I) or Overall Efficiency = 1-((Electric Current-Shunt Field Current)^2* Armature Resistance + … WebFeb 8, 2024 · The humble current shunt is an excellent way to do just that. Ohm’s Law. ... The power lost in the resistor is equal to the current squared, multiplied by the resistance. .
