Circuit with resistors in series producing fraction of source voltage
Vout=Vin×R2R1+R2V_{out} = V_{in} \times \frac{R_2}{R_1 + R_2}Vout=Vin×R1+R2R2
Decreases current, reducing VoutV_{out}Vout across R2R_2R2
Increases current, raising VoutV_{out}Vout
Decreases
Decreases (in most cases)
LDR resistance increases, VoutV_{out}Vout reduces
Automatically turn on street lamps as it gets dark
Regulate heating systems
In series
