why doesn't capacitance decrease with increase in temperature??
It is known that conductivity increases with temperature.This is because heat provides kinetic energy to the electrons in a substance,thus increasing the rate of "flow" of electrons.Considering this,the electrons in a dielectric in a capacitor should also get excited on heating.This means the electrons are more likely to break away from one end and would travel to the other end.This means that the CAPACITY OF THE DIELECTRIC TO RESIST THE FLOW OF CHARGES[which in fact the capacitance of dielectric in the given set up] MUST DECREASE,WITH INCREASE IN TEMPERATURE.
am i right or is there something more to it??
please help me.
