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 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.
How is the resistance of an LDR affected by a light intensity?
The resistance of an LDR (Light Dependent Resistor) decreases with increasing light intensity. This is because more photons striking the LDR cause more electrons to be released, increasing its conductivity and lowering its resistance.
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.
In technology what does LDR stand for?
LDR stands for Light Dependent Resistor. It is a type of resistor that changes its resistance based on the amount of light that falls on it. This change in resistance allows LDRs to be used in light-sensitive applications, such as automatic lighting controls.
When an LDR detects light or dark how long does it take for its resistance to change?
20 seconds

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 is the function of an LDR or a TDR in an circuit?
The function of an LDR or light dependent resistor is to change the brightness of the light based weather conditions or light hitting the object the LDR is on. When it is darker out, the light does not shine as brightly.
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.
When its bright does an LDR have a high or low resistance?
When it is bright, a Light Dependent Resistor (LDR) has low resistance. LDRs are designed to decrease their resistance in response to increased light levels, allowing more current to flow through them. Conversely, in low light conditions, their resistance increases. Thus, the resistance of an LDR is inversely proportional to the intensity of light it receives.
Why does potential difference across a LDR with changes its resistance?
The resistance of a Light Dependent Resistor (LDR) changes due to its sensitivity to light intensity. When light falls on the LDR, photons excite electrons, reducing the resistance as more charge carriers become available for conduction. Consequently, as the light intensity increases, the potential difference across the LDR decreases, as it allows more current to flow for a given voltage. Thus, the potential difference varies inversely with the resistance of the LDR under changing light conditions.
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.
