What changes occur to voltage-gated Na and K channels at the peak of depolarization?

Inactivation gates of voltage-gated Na+ channels close, while activation gates of voltage-gated K+ channels open.


What is ups static switch?

In uninterruptible power supply (UPS), it is an electronic switch used to bypass a mechanical switch. Normally used when loads are switched from inverter to mains.Static switch is an automatic switch that can only be activated depending on the condition of the UPS.The following are the conditions wherein the UPS static switch can be activated:1. Overload condition2. Failure of inverter3. Availability of UPS bypass supply but absence of UPS rectifier supply (normal UPS power) that ran out its battery.4. Manual intervention on the UPS that resulted to the activation of static bypass switch.


What is Automobile Gas Pedal an analog system or an digital system?

In carbureted cars, this is completely an analog function, from pedal to carburetor throttle body. On electronic fuel injected cars, this is part analog and part digital. The part where your foot controls the position of the accelerator is analog, then this position information is digitized and sent to the cars control computer where the position information is translated into an engine RPM request. This digital request is sent to a sophisticated fuel/air control algorithm which increases/decreases the injector activation control period in relation to the volume of in rushing air measurement. The digital side of an injection control scheme is a pretty delicate balance of engine part design knowledge, such as cam lift/open duration/close timing. This is why if you change a physical feature of an engine that is computer injection controlled, the computer needs to be reprogrammed in order to take advantage of the change.


Why do you need a shunt trip breaker?

A shunt trip breaker is installed like any other molded case breaker. The only difference is that it has an internal tripping coil that is usually connected to a C.T. The breaker is usually mounted in a MCC cabinet The top of the breaker is bolted to the MCC bus bars and the bottom of the breaker is connected to the load. The load conductors pass through the C.T.'s which induces a current into the circuit to trip the tripping coil in the breaker.
