Physics question.....

[niassu]

plz any one can explain what is the use of the:
1. Capacitor
2.temperature sensitive switch (using thermistor,transistor,potential divider)(Q-what would ghapper if the resisitor used in he potential divider is reduced)

 

[niassu]

heeeeeeeeeeeeeeeeelllllllllllloooooooooo is any body here

 

[Igcse100]

Capacitor stores electric charges and is useful in many electronic circuits.

The second question isnt much clear could u kindly elaborate.

In the name of Allah begin your difficult tasks as he is the one who provides us with knowledge

ya sorru i've typed it wrong i mean do u have any info.abt the temp.switch(potentail divider which uses a thermistor)

If you mean what the functions of (1) capacitor and (2) thermistor in a potential divider for a transistor circuit, then the answer is:

(1) Automatic timer (e.g., for windscreen wiper on intermittent, or time-lock devices, etc)

(2) Automatic switch based on temperature (e.g., air-conditioner, heater, oven, refrigerator, etc.)

Depending on whether it is connected in the base circuit, it will be used to switch on / off the collector circuit when [capacitor reaches full charge] / [thermistor detects high temperature].
