Variables
What you change
- Capacitors Values
What you measure
- Total Capacitance
What you keep constant
- Wire length
- Wire cross section
- Temperature of wire
Equations
C_eq = Equivalent capacitance (uF)
C_1 = First capacitor Capacitance (uF)
C_2 = Second capacitor Capacitance (uF)
In Parallel: C_eq = C_1 + C_2
In Series: \frac{1}{C_eq}= \frac{1}{C_1}+ \frac{1}{C_2}
What You'll Need

Mind-Blowing Fact
Discharge.
Touchscreens work by emitting electricity, which your finger absorbs. This is known as capacitive technology and it is how your phone knows the difference between you and an inanimate object.
