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.

What happens to the barrier potential when the temperature increases?
When the temperature increases, the barrier potential in a semiconductor diode decreases. This is due to the increase in carrier density at higher temperatures, which results in more charge carriers being available to pass through the barrier. Ultimately, this leads to a lower resistance across the diode and a decrease in the potential barrier.
What happens to the partial pressure of oxygen in a sample of air when the temperature increases?
When the temperature of a sample of air increases, the partial pressure of oxygen also increases.
What happens to a gas temperature when you put it under pressure?
When a gas is put under pressure, its temperature typically increases. This is because compressing the gas increases the kinetic energy of its molecules, leading to an increase in temperature.
What happens to a gas's thermal energy as that gas's temperature increases?
As the gas's temperature increases, its thermal energy also increases. This is because temperature is a measure of the average kinetic energy of the gas particles, and as they move faster (due to higher temperature), they possess more kinetic energy and thus the thermal energy of the gas increases.
Is barrier potential temperature dependent?
Yes, the barrier potential in a semiconductor diode is temperature dependent. As temperature increases, the barrier potential decreases due to changes in the band gap energy and carrier density, leading to increased leakage current. Conversely, as temperature decreases, the barrier potential increases, reducing the leakage current.
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 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 when temperature?
rate 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 when one of three diode is removed from 3 phase full wave rectifier?
A: Then the phase that the diode is remove will not work or Rather get an output
What happens to volume as temperature changes?
if volume of a gas increases temperature also increases
What happens when rust occurs?
temperature increases.
What happens when stream temperature increases?
It freezes.
