Thermistor Questions:

Question #1:

Why the resistance of a thermistor decreases with increase in temperature?

Question #2:

Describe the action of thermistors and light dependent resistors !?

Question #3:

AS PHYSICS--Please help me figure out how many marks I would get with this answer?

Q3b

PAPER


MARK SCHEME


My answer
from the leveling V=IR we crapper wager that V possibleness disagreement and R status has the a progressive relationship so as the p.d crossways the thermistor accumulated so did the resistance. As it's a program circuit both the thermistors and immobile resistors's underway is the aforementioned so the p.d across the fixed resistance must also increase.

Please explain where I forfeited the marks or if I hit got it completely wrong

and I would also be rattling grateful if anyone could help me with the second part of the question

Question #4:

How are thermistors of negative temperature coefficient type and light-dependent resistors used as input?

sensors?

Question #5:

Thermistor Circuit do not understand questons?

I hit been employed on circuits in nonconvergent and program but I having a hard instance discernment this digit in portion question a c f


please vindicate travel by step
I dont see when I utter on it and click zoom it looks fine what is the problem?
Thanks!!!

Question #6:

Thermistor circuit question?

I have been employed on circuits in parallel and program but I having a hard time understanding this one in particular discourse a c f

sorry guys here is the actual link it got scanned strange

can I please telecommunicate one of you guys because this is a scanned product and I do not know how added to attain it viewable. I am doing it through picasa online

Question #7:

refrigerator problem?

I poverty to change the thermistors on my GE strikingness Artic refrigerators. There is digit in the lateral panel of the icebox area. Do I just cut and slice? and use accommodate nuts? It does not countenance same a regular plug in type. I needed a newborn care board and the fixer live me for these parts, so I thought I would replace them.
Thanks, Gary

Question #8:

My 2002 honda civic ex is overheating?

my subject started overheating and i found out i had a crack in my radiator so i replaced it, then about a hebdomad after it started overheating again, some of the issues seemed to be pointing to the thermostat so i replaced that but its ease overheating, my fans don't squawk on at all unless i separate my ac, so im def intellection a fan issue now, but also when i run the heat exclusive modify air comes out and it doesn't help cool the engine downbound same streaming the heat should do..i also put a teenager on my thermistor for my ac because i had a short and it fixed my difficulty but would modifying my thermistor mess with my heat

Question #9:

How does the resistance change?

How does the status modify when I shine brighter reddened on:
an LDR
a Thermistor
a Diode

How does the resistance modify when I heat up
an LDR
a thermistor
a diode

Thanks!

Question #10:

Why won't my refrigerator get colder than 46 degrees?

I hit a 6-7 year older GE Profile freezer on the bottom, help #PDS22MCRBCC. I didn't wager any ice build-up but overturned the organisation off for threesome days just in case there was build-up I couldn't see. After plugging the unit back in it had the aforementioned problem. I replaced the semiconductor as well and ease null colder than 46 degrees. Freezer works fine.

I also hit a thick, sticky yellow goo that has been unseaworthy discover of the accolade at the lower left crossway between the outer bomb of the refrig and freezer wall. Believe this is insulation that didn't accustom during the manufacturing or has softened over time. Not trusty if this could be restricting the flowing somewhere in the unit.

Any ideas?
