What else can I help you with?
CAN LDRs be connected in parallel?
yes the ldr can be connected in a paralell circuit as i have done a experiment about te ldrs
What type of circuit normally contains LDR?
LDRs are normally found in Light/Dark sensing circuits
What is the difference between LDR and LED?
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.
What is the purpose of the diode in the GM AC clutch circuit?
The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit. The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit.
What type of signal output produced by LDR?
A light-dependent resistor (LDR) produces a variable resistance output based on the intensity of light it is exposed to. In low light conditions, the resistance of the LDR is high, resulting in a lower current flow, while in bright light, the resistance decreases, allowing more current to flow. This change in resistance can be used to generate an analog voltage signal when connected to a circuit, making it useful for light-sensing applications.
What will the decrease of the light intensity on an LDR do to the ammeter reading?
The decrease of light intensity on an LDR will cause the resistance of the LDR to increase, which will result in a decrease in current flow through the circuit. As a result, the ammeter reading will decrease.
What is purpose THE LDR?
I don't know. If i knew then i wudn't b askin!!!!
What does an LDR do in a circuit?
An LDR is a 'light-dependant resistor'. It's one of the devices sometimes called "photocells", but the LDR doesn't generate anything. It only changes resistance depending on the intensity and wavelength of the illumination falling on it. The simplest application would be in a circuit that switches something on or off to correspond with daylight and darkness. Somewhat fancier applications might include ... -- monitor a light beam across the door of a store, to ring a bell when a customer walks in; -- detect the audio carried on an amplitude-modulated light beam.
Is there a simple circuit using LDR for an automatic headlight dimmer in vehicles?
Yes, a simple circuit using a Light Dependent Resistor (LDR) can be designed for an automatic headlight dimmer in vehicles. In this setup, the LDR detects ambient light levels; when it gets darker, the resistance of the LDR decreases, triggering a relay or transistor to switch the headlights on or dim them as needed. This can be combined with a potentiometer to adjust the sensitivity of the dimming effect, allowing for customization based on the driver's preference.

What is the principle of operation of LDR?
Working of light dependent resistor This circuit explains the principle of operation of LDR (light dependence resistor). The circuit has various applications like shadow alarm, automatic night/morning lamp. LDR, an acronym for light dependent resistor is a resistor whose resistance is dependent on light. The resistance of LDR is of the order of Mega Ohms in the absence of light and reduces to a few ohms in presence of light. In this circuit when the light falls on LDR, the resistance of LDR becomes low and the entire voltage drop takes place across the variable resistance VR1 (10K). As a result the base of transistor (T1) gets high input and it gets biased thereby glowing the LED. When no light falls on LDR, the resistance of LDR becomes high so almost entire voltage drop takes place across it and the base of transistor is at low potential. So transistor does not gets biased nor it becomes conducting, hence switching off the LED. The sensitivity of the circuit can be adjusted by varying the preset VR1.

The purpose of a Light Dependent Resistor (LDR) is to change its resistance based on the intensity of light falling on it. This property makes it useful in applications such as automatic lighting control, photography, and light-sensitive alarms.
