A Light Dependent Resistor (LDR) is not considered an ohmic conductor. Ohmic conductors follow Ohm's Law, where the current through the material is directly proportional to the voltage across it, resulting in a constant resistance. In contrast, the resistance of an LDR changes with varying light intensity, leading to a non-linear relationship between voltage and current. Thus, its behavior does not conform to ohmic characteristics.

An LED is an electircal component which converts electrical energy into light energy whereas an LDR uses light to complete the circuit and maintain the flow of current.
A photoresistor, light dependent resistor (LDR) or cadmium sulfide (CdS) cell is a resistor whose resistancedecreases with increasing incident light intensity. It can also be referred to as a photoconductor.Applications:camera light meters, street lights, clock radios, alarms, and outdoor clocks
yes the ldr can be connected in a paralell circuit as i have done a experiment about te ldrs
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.
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.

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.
An LDR is a Light dependent resistor.
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.
LDR refers to Light Dependent Resistor.
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.
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.
Light Dependent Resistor LDR also means long distance relationship.
The symbol for LDR Holding Corporation in NASDAQ is: LDRH.
