Why does the resistance of a thermistor decrease as the temperature rises?
Some materials have negative temperature coefficients of resistance, and some have positive temperature coefficients. Carbon is an example of a substance with a negative thermal coefficient of resistance, so it's resistance will decrease as it gets hotter.
How ujt exhibits negative resistance characteristics?

What is the difference between positive and negative temperature coefficient of resistance?
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.
Which diode does not use negative resistance in its operation?
Backward diode
Why it is said to be negative resistance region?
A negative resistance region is where the current goes up while the voltage goes down, or vice versa. This is a characteristic of the esaki or tunnel diode, when it is in its tunnel region.
When was Hugo Tetrode born?
Hugo Tetrode was born in 1895.
When did Hugo Tetrode die?
Hugo Tetrode died in 1931.
What is a tetrode?
A tetrode is an electronic tube with four electrodes; cathode, grid, screen, and plate.
Why you use tetrode instead of triode?
a tetrode is used when you need a screen grid tube, but a suppressor grid tube can't be used.OK, but the question was "why use a tetrode instead of a triode?"So, the answer...1. A tetrode has a higher voltage/power gain than a triode.2. A tetrode has less anode-grid feedback capacitance than a triode, and can operate in common-cathode radio frequency circuits without the neutralisation (or other corrective circuitry) that is needed by a triode.
What is the tetrode?
Twin-grid vacuum tube
What is negative resistance region?
The region where resistance decreases with increase in temperature.

What are names of the original papers of Otto Sackur and Hugo Tetrode published in 1912-1913?
Tetrode original paper: Die chemische Konstante der Gase and das elementare Wirkungsquantum I don't know about Sackur
What 7 letter word can you make with ottered?
