Variables
What you change
- Resistance value
What you measure
- Voltage Drop
What you keep constant
- Wire length
- Wire cross section
- Temperature of wire
- Transformer Nature
- Rectification Type
Equations
V_1 = Voltage drop on first resistor (V)
V_2 = Voltage drop on second resistor (V)
R_1 = First resistor (ohm)
R_2 = Second resistor (ohm)
V_1=(\frac{transformer output voltage}{R_1+R_2})*R_1
V_2=(\frac{transformer output voltage}{R_1+R_2})*R_2

Mind-Blowing Fact
Look deep within.
A 1$ microscope can be made that can magnify by 140x to 2000x using a punched sheet of cardstock, a spherical glass lens, a light emitting diode, diffuser panel and a watch battery.
