When light falls on ldr resistance is increasing why?

When light falls on an LDR (Light Dependent Resistor), more photons are absorbed by the semiconductor material in the LDR, causing more electron-hole pairs to be generated. This increases the conductivity of the material, resulting in a decrease in resistance. Hence, the resistance of an LDR decreases with an increase in light intensity.


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 happens to the value of an LDR when a bright light shines upon it?

The resistance of an LDR (Light Dependent Resistor) decreases when a bright light shines upon it, causing its conductivity to increase. This change in resistance is due to the light intensity affecting the number of charge carriers in the semiconductor material of the LDR.


What is an LDR symbol?

An LDR is a Light dependent resistor.


What material is used to fabricate ldr?

Light-dependent resistors (LDRs) are typically made from cadmium sulfide (CdS), a semiconductor material that exhibits changes in resistance in response to changes in light intensity. This unique property allows LDRs to be used in various light-sensing applications.


What is the meaning of LDR?

LDR refers to Light Dependent Resistor.


How does light affect LDR?

An LDR is a light dependent resistor, which is usually used to detect light levels, either ambient or reflected. The LDR works because incoming light carries energy, which can elevate the energy levels of electrons in a suitable medium to join the 'conduction band' which means that there are more charge carriers in the LDR, and hence the cell has lower resistance.


What happens to an LDR when a bright light is shined upon it?

When LDR is exposed to light energy . Due to light energy incident on LDR surface, free electron movement of an atom is increased in LDR. This causes high conduction of curent flowing through LDR. beause of free electron movement in LDR, resitance get decreased.


What does LDR stand for?

Light Dependent Resistor LDR also means long distance relationship.
