What reading level is Alternating And Interrupted Electric Currents : Being Based Upon Three Lectures Delivered to the Members of the Royal Institution book?
To quickly assess the difficulty of the text, read a short excerpt:
If the cable which we wish to imitate has 800 microfarads capacity, the permanent charge on it would be — -i xl00=0'08 coulomb. Fixing now the lower «nd of the thread, apply the air-jet and observe the twist. Suppose it is ten revolutions. Then one revolution means O'OOB coulomb, and one revolu- tions per second means O'OOB ampere. If now the resistance of the cable be 6,000 ohms, the permanent current would be ampere. This should be represented by = = two ^ ^ 60x0-008 0-48 revolutions per seco...nd. Leave now the lower end free, and apply the air-jet at the top. If you get two revolutions per second, you have the right resistance in the model. If not, add more water or glycerine till you get it right.
You cannot, however, get mirror signals thus, as ELEOTEIC CURRENTS. 37 velocity indicates current, and the zero would, move. If, however, you put a mirror at the lower end of the thread, and restrain its motion either by a spring or by magnets, you are putting in a receiving condenser, and the deflection indicates the- potential at that point of the cable, just as a- recorder does.
