Which of the following components exhibits a temperature dependent resistance?
resistor
diode
thermistor
|
As the temperature of a thermistor increases, its resistance will:
remain the same
decrease
increase
fluctuate randomly
|
In an NTC thermistor, NTC stands for:
neutron tunneling conductor
nuclear time constant
non-thermal conductor
negative temperature coefficient
|
An LDR exhibits a resistance that varies with:
current
light intensity
magnetic field strength
voltage
|
As light intensity on an LDR increases, its resistance will:
decrease
remain unchanged
increase
fluctuate randomly
|
Increased light intensity on an LDR leads to:
more charge carriers
no change in charge carriers
random charge carrier fluctuations
fewer charge carriers
|
Adding energy to a semiconductor:
increases conductivity
has no effect on conductivity
causes random conductivity fluctuations
reduces conductivity
|
What is the name for components with temperature dependent resistance used in sensing circuits?
|
Give 2 effects of increased light intensity on an LDR.
