Relation Between Voltage And Light Using LDR
Effect of light intensity on the resistance of an LDR.
Part of the course: Electronics & Sensing — Diodes, Light & Infrared
Mission
The effect of light intensity on the resistance of an LDR.
Variables
What you change
- Light intensity
What you measure
- Voltage Drop
What you keep constant
- Wire length
- Wire cross section
- The voltage of the power source
- Temperature of wire
Equations
V_Bat = Battery Voltage
V_LDR = LDR Voltage
V_R = Resistance Volage
V_Bat = V_LDR + V_R
