The temperature drop across the coil is dependent on the relative humidity of the air, the wet bulb reading of the R/A, and the ambient temperature of the home. But a good rule of thumb is in between 17 and 22 degrees Fahrenheit.

What is the expected temperature drop through a direct expansion evaporator coil is?
The expected temperature drop through a direct-expansion evaporator coil is 20°F. The evaporator coil became clogged during the adjustment period.
What would happen if the current passing through the coil was too large?
The coil offers some amount of Resistance to the flow of Electric current through the coil. The Resistance of the coil depends on the material used to make the coil and the thickness of the coil wire ( its gauge ) When a current flows through the coil, the voltage drop across the coil and the Power dissipated in the coil both are proportional to the magnitude of current and the coil resistance. Normally the coil is rated to carry certain current and dissipate certain amount of power without causing any damage. If a large magnitude of current flows through the coil beyond its rating , the voltage drop across the coil and the power dissipation in the coil both increase substantially causing over heating of the coil. This can damage the coil and may result in burning of the coil
Is this a stimulus or response a sudden drop in air temperature?
A sudden drop in temperature would be a response to a stimulus.
What is the temperature drop from 8 Fahrenheit to -17 Fahrenheit?
The drop is 25 degrees.
What is the temperature when a tornado happens?
There is no particular temperature at which tornadoes happen, but they are most common on hot days and are often followed by a temperature drop.
How is the temperature drop through a direct expansion coil on an air conditioning system determined?
It is determined through measurement and temperature.
What is the expected temperature drop through a direct expansion evaporator coil is?
The expected temperature drop through a direct-expansion evaporator coil is 20°F. The evaporator coil became clogged during the adjustment period.
Why is the evaporator in a central air unit freezing up?
Low Ambient Temperature.The mechanical refrigeration system used in air conditioning equipment is design to work when the outdoor temperature is above 65°F. If the AC runs when the temperature is too low will cause the evaporator coil to drop in temperature and freeze over. BigBOB
What is the typical voltage drop across a photodiode?
The photodiode's voltage drop varies with the temperature and current flowing through it. The typical voltage drop (VBIAS - VREF) across the MAX4007 series is 0.8V, with a guaranteed maximum of 1.1V.
At high temperature the forward voltage drop across a diode can be expected to be more or less than it is at low temperature?
high temp
How would you measure a relays contacts resistance?
The voltage drop across a relay coil will be the same as the coil supply voltage. If you are trying to see if the coil is good or not, remove one of the voltage supply leads and check for continuity by using an ohm meter across the coil leads. A reading will tell you that the coil is intact and not open.
Is my lava lamp broken if the coil is detached from the bottom and moving around?
I was reading about my lava lamp because i haven't used it in years and wasn't sure if they "went bad" after a while. And i came across a site that said,"The coil should then automatically drop to its correct position (after 4 hours or more) at the bottom of the globe. If the coil does not drop down, twirl the globe gently in the base and the coil will drop.". So, I'm assuming the coil is supposed to be free flowing. hope that helps! and here is the website that has the info: http://www.coolstuffcheap.com/lavalampfaqs.HTML

What causes low temp drop across evaportor coil on central AC unit?
The most likely causes would be: defective expansion valve low refrigerant (generally as a result of a leak) contaminant buildup on the inside of the coil
Why does your AC unit freeze up?
There are 4 reasons why an A/C system will freeze up. The first and most common is dirt. A dirty filter or evaporator coil will restrict airflow which lowers evaporator coil temperature (Near furnace inside). A dirty blower wheel will not move enough air either. Second is low refrigerant. Third is the least common and most expensive to find and repair. A restriction in the refrigerant system. If you have a restricted metering device in the evaporator coil or anywhere else in the system it will cause a temperature drop across the restriction. How much of a drop depends on how bad the restriction is. Reason 4 is a bad contactor on your outside unit that is not allowing it to turn off when the furnace turns off.
Does the temperature rise or drop in the thermospere?

Does the temperature rise or drop in the stratosphere?
