ZT is the dimensionless figure of merit and its value, ranging from 0.2 to 2, varies with temperature. The efficiency calculated according to the theoretical model (Eq.
A GUIDE TO LOW RESISTANCE TESTING
www.testequipmentdepot.comuses Manganin alloy because it has a low temperature coefficient so that its resistance changes very little with temperature (see figure 1). The table below from Melvin B. Stout’s “Basic Electrical Measurements” highlights the key properties of Manganin. The thermal emf against copper indicates the thermocouple
