Abstract
Transient effects on electrical energy measurements in calorimetry will be minimized if P, the power developed in the heater, satisfies the condition dP/dR=0, where R is the resistance in which the power is developed. It is shown that this condition is satisfied if the resistance U between the two points of the supply network to which R is connected is kept equal to R. Circuits for maintaining this condition are described.Keywords
