Method
Investigate how changing the resistances and the supply voltage affects the voltages across each resistor.
Choose a supply voltage V
s
.
Adjust R
1
and R
2
using the sliders.
Read V
1
(voltage across R
1
) and V
out
(voltage across R
2
).
Predict the output before moving each slider — check your reasoning.
Try the LDR or thermistor option to see how light or temperature affect V
out
.
Record readings in the table and export a CSV.
