What is an open drain called?
An open channel or drain system generally consists of a secondary drainage system, with a network of small drains attached (micro-drainage). These small drains bring the water to a primary drainage system, composed of main drains (also called interceptor drains), which serve large areas of the city.
Is open collector sinking or sourcing?
While the NPN open collector transistor circuit produces a “current-sinking” output, that is the NPN transistors open collector terminal will sink the current to ground (0V), a PNP-type transistor can also be used in an open collector configuration to produce what is called a “current-sourcing” output.
Why is open drainage harmful?
If the open drains are left unchecked, they become a health hazard to the neighboring population as they become a breeding ground for disease-causing parasites and other microorganisms. And when the rainy season begins, the open drains can rapidly spread water-borne diseases and infections.
What are the effects of poor drainage?
Poor drainage can lead to flooding, resulting in property loss, and people may even be forced to move to escape floodwaters. Flooding may also damage water supply infrastructure and con- taminate domestic water sources.
What is an open drain?
An open drain is an open channel, mostly found in urbanized areas and used for the discharge of rainwater. Rainwater collected by the channels is often directed to rivers or other water sources. Drains serve a good purpose in preventing flooding but when they lack covers as it is the case for open drains,…
What is an open collector?
Open collector. A simple schematic of an open collector of an integrated circuit (IC). An open collector is a common type of output found on many integrated circuits (IC), which behaves like a switch that is either connected to ground or disconnected.
What is open drain FET?
The term “open drain” means there’s a current sink, but on a FET device, for example, a MOSFET . (A MOSFET is like a transistor that can handle higher voltages but operates in much the same way.)
