At increasing frequency, on the other hand, the reactance increases and at a sufficiently high frequency the inductor approaches an open circuit. Source: Internet
Apart from testing the open circuit voltage of the thermocouple, and the near short-circuit DC continuity through the thermocouple gas valve coil, the easiest non-specialist test is substitution of a known good gas valve. Source: Internet
Although he coined the most common English word used for autonomous open circuit diving equipment, Lambertsen did not invent that equipment. Source: Internet
During the 1940s, Cousteau is credited with improving the aqua-lung design which gave birth to the open-circuit scuba technology used today. Source: Internet
However its large inductance gives it a very high impedance at the resonant frequency, so it acts as an open circuit to the oscillating current. Source: Internet
In Britain the word aqualung, used for any demand-valve-controlled open-circuit scuba set, still continues to be used nowadays; in old times it was sometimes inaccurately for any scuba set including rebreathers. Source: Internet
