In technology what does LDR stand for?
LDR stands for Light Dependent Resistor. It is a type of resistor that changes its resistance based on the amount of light that falls on it. This change in resistance allows LDRs to be used in light-sensitive applications, such as automatic lighting controls.
What are the independent dependent and control variables in series circuit containing 1ammeter a resistor a light bilulb and 3cells?
Independent variable: the number of cells in the circuit. Dependent variable: the current measured by the ammeter. Control variable: resistance of the resistor, type of light bulb.
What is the symbol for ldr?
The symbol for Light-Dependent Resistor (LDR) is a resistor symbol with photo-sensitive material added to one side. It looks like a regular resistor with one side having a shaded area to represent its light sensitivity.
What is a use of a ldr?
A Light Dependent Resistor (LDR) is used in various applications to detect the presence or absence of light. It is commonly used in automatic lighting systems, camera exposure controls, and streetlights to adjust the intensity of light based on the surrounding conditions.
When was the resistor invented?
Otis Boykin invented the resistor in 1959.
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.

What are the advantages and disadvantages of light dependent resistor?
itroduction on LDR
What is the meaning of LDR?
LDR refers to Light Dependent Resistor.
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.
