In technology what does LDR stand for?
Light dependent resistor.
When was the resistor invented?
Otis Boykin invented the resistor in 1959.
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
What is the use of photoresistors?
Photoresistors also known as light dependent resistor (LDR) are used to increase light intensity by decreasing resistance. This is applied to camera lights, street lights, solar street lamps.
How do you measure light intencity?
Measure Light Intensity using Light Dependent Resistor (LDR) The resistance of the Light Dependent Resistor (LDR) varies according to the amount of light that falls on it. The relationship between the resistance RL and light intensity Lux for a typical LDR is RL = 500 / Lux Kohm With the LDR connected to 5V through a 3.3K resistor, the output voltage of the LDR is Vo = 5*RL / (RL+3.3) Reworking the equation, we obtain the light intensity Lux = (2500/Vo - 500)/3.3 For a low cost LDR, at the same light intensity, the part to part variation in resistance can be as high as 50%. Therefore such a low cost LDR is seldom used for measuring light intensity but more for light presence/absence detection.
Who invented light dependent resistor?
K. K.
How do you set the sensitivity of a light dependent resistor?
using a variable resistor we can adjust the sensitivity of a light dependent resistor
Is Light dependent resistor an example of resistor?
yes, a variable resistor
What is an LDR symbol?
An LDR is a Light dependent resistor.
In technology what does LDR stand for?
Light dependent resistor.
What is the meaning of LDR?
LDR refers to Light Dependent Resistor.
What are the advantages and disadvantages of light dependent resistor?
itroduction on LDR
Materials required to study light dependent resistors?
a resistor , two multimeter ,
What is a light dependent resister?
As light falls on the conductor then emission of electrons would increase the conductivity and so its resistivity decreases. Such a conductor is known as light dependent resistor.
Where are light dependent resistors used for?
Its slows down energy when it passes thought the light depntent resistor.
What is a LDR dependent AC dimmer?
The LDR dependent AC dimmer is a Light Dependent Resistor which works by chopping off the parts of the AC voltage.
What is the purpose the light dependent resistor?
This is a Resistors,who's resistance decrease when light energy falls on its surface gradually.
