Answer Wiki. Practically, A source is modeled as an idea voltage source in series with a source resistance(due to the source components, connecting wires etc.). The terminal voltage measured at the source terminals will be less than the actual source voltage itself due to voltage drops in the series resistance. Rs needs to be considered whenever you do a practical design for the SCR as there is an upper limit to the amount of current the SCR can handle at the Gate Terminal given by Es/Rs.
The abyssal zone or abyssopelagic is a layer of the pelagic zone of the ocean. Abyss derives from the Greek word á¼Î²ÏÏÏÎ¿Ï, meaning bottomless. At depths of 4,000 to 6,000 metres (13,000 to 20,000 ft), this zone remains in perpetual darkness and never receives daylight. These regions are also characterised by continuous cold and lack of nutrients.The abyssal zone has temperatures around 2 to 3 Â°C (36 to 37 Â°F) through the large majority of its mass. It is the deeper part of the midnight zone which starts in the bathypelagic waters above.
In a cool climate (outside the ocean), the temperature can be below freezing, but in a really warm climate, this zone can have warm waters. The pelagic zone: -- This zone is generally a warm zone, however, because warm and cold currents are constantly mixing, it can be cold in some parts and cooler in others.The benthic zone: -- The temperature of this zone is colder than the pelagic zone and is pretty much always cold.The abyssal zone: -- This zone is the coldest of all of the zones.Because no sunlight reaches this zone the water is never heated.n a cool climate (outside the ocean), the temperature can be below freezing, but in a really warm climate, this zone can have warm waters.
