Light-dependent resistors (LDRs) are commonly used in schools for various applications including automatic lighting systems, science experiments related to light intensity, and in circuit design projects to detect light levels. They are advantageous due to their sensitivity to light and ease of integration into circuits for educational purposes.

What type of LDR commonly used in schools?
A common type of LDR (Light Dependent Resistor) used in schools is a photoresistor. It changes its resistance based on the amount of light it is exposed to, making it useful for projects involving light sensing and control. Students often use photoresistors in science experiments or electronics projects to learn about light-dependent behavior.
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.
What is the function of a light dependent resistor?
The resistance of LDR increases when light is not available (or is limited). And the resistance drops when Light is abundant.This principle can be used in proximity detectors where one or more light source(s) is/are active. When a person / object comes in proximity of the source, the light gets reflected from the object-surface & can now be received by LDR. So due to proximity of the object, resistance of LDR changes - this can be used to trigger different actions like open the door, trigger a motor. Fire an alarm. etc.Resistance of LDR varies according to intensity of incident light over it,It is used in street light to detect day/night and turn on/off the street light automatically
What does LDR change as the what intensity changes?
As the light intensity increases, the resistance of an LDR (Light Dependent Resistor) decreases. This means that the LDR becomes more conductive and allows more current to flow through it. Conversely, when the light intensity decreases, the resistance of the LDR increases, reducing the current flowing through it.
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.

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.
