WebAug 26, 2009 · — The experiments with cooling in a refrigerator gave favourable results after 8 weeks at 5° C; 4 weeks were less effective; 2 weeks or 1 week were ineffective. Humidity conditions, either constant at 56, 76 or 90 per cent r.h. or variable, had only a small influence on pupation. In an RL circuit composed of a single resistor and inductor, the time constant (in seconds) is where R is the resistance (in ohms) and L is the inductance (in henrys). Similarly, in an RC circuit composed of a single resistor and capacitor, the time constant (in seconds) is: WebAug 10, 2024 · Hi, Cosmos Omondi here. I'm an HVACR freelance writer.
