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.
There is no light in the Abyssal Plain because the dept in meters is 3000-6000 and light from the surface cannot reach that far down. SALT The amount of salt changes throughout this ecosystem. The salt level is between 34 and 35 parts per thousand. Which is 3.4%- 3.5% salt!
