When the amount of current passing through a circuit increases, it generally increases the temperature, and consequently the resistance. Simply stated, it is harder for the current to pass through the circuit if the temperature increases. The Large Hadron Collider uses superconductors to pass current to its electromagnets. A superconductor passes current through its circuit materials with almost no resistance at all, generally by supercooling the circuit materials.

∙ 12y agoThe resistance of a semiconductor junction drops at high temperature due to creation of additional current carriers, electrons and holes, and if the device gets too hot the lowered resistance may cause an uncontrolled current flow resulting in even more heating and destruction of the device.

When temperature increases what happens?
The level of thermodynamic energy increases.
What happens to a gas's thermal energy as that gas's temperature increases?
It increases.
What happens to the temperature while the water is in the process of freezing?
the temperature increases
What happens to its volume when the temperature of a gas increases at constant pressure?
The volume increases.
What happens to strength when temperature of solid metal increases?
The pressure at which it yields is reduced as the temperature increases
What happens when the temperature of a forward biased diode is increased?
What happens depends on the temperature coefficient of the diode. If that diode has a positive temperature coefficient, it resistance increases with increased temperature. A diode with a negative temperature coefficient does the opposite.
How does the ac resistance of a diode change as the voltage increases?
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
When temperature increases voltage across diode with constant current?
The voltage across a semiconductor diode (and across the base/emitter junction of a transistor) decreases as temperature increases: the actual figure is -2mV/°C.
What happens to the amount of oxygen carried by hemoglobin as temperature increases?
"What happens to the amount of oxygen carried by hemoglobin as temperature increases?" "What happens to the amount of oxygen carried by hemoglobin as temperature increases?" "What happens to the amount of oxygen carried by hemoglobin as temperature increases?"
What happens to the ability of a solid to dissolve in a liquid if the temperature increases?
It increases as the temperature increases.
What happens to the solubility to the solid when the temperature increases?
It increases !
What happens to temperature in the thermosphere when altitude increases?
It increases.
What happens to the volume of mercury as the temperature increases?
The volume increases, which is why the mercury in a thermometer rises as the temperature increases.
What happens when temperature?
rate increases
When temperature increases what happens?
The level of thermodynamic energy increases.
What happens to solubility of a substance when their is rise in temperature?
Generally, as temperature increases, solubility increases. There are a few cases where the opposite happens, though.
What happens to a gas's thermal energy as that gas's temperature increases?
It increases.
