There are important mineral and thermal springs in various parts of the island.
We assume that each carbon atom and each hydrogen atom contributes equally to the thermal effect.
At the receiving station the differences in these systems depend chiefly upon variations in the actual form of the oscillation detector used, whether it be a loose contact or a thermal, electrolytic or magnetic detector.
It follows that the thermal effects stated above must be equal, i.e.
The thermal G G detectors are especially useful for the purpose of quantitative measurements, because they indicate the true effective or square root of mean square value of the current or train of oscillations passing through the hot wire.
