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
LDRs are normally found in Light/Dark sensing circuits
yes the ldr can be connected in a paralell circuit as i have done a experiment about te ldrs
automatic
industrial automaton
this is the symbol for ldr
An LDR is a Light dependent resistor.
Basically, ETC
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.
Light Dependent Resistor LDR also means long distance relationship.
The symbol for LDR Holding Corporation in NASDAQ is: LDRH.
LDR Holding Corporation (LDRH) had its IPO in 2013.
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.
