Learning Goals: Students will be able to:
Identify the variables that affect the capacitance and how each affects the capacitance.
Determine the relationships between charge, voltage, and stored energy for a capacitor.
Relate the design of the capacitor system to its ability to store energy. Equipment (for real life “build”)
2 sheets of aluminum foil A couple of papers for Dielectric
A Multimeter (with an ability to measure capacitance)
1. Building a Capacitor
Imagine that you are stuck at home, can’t leave the house, and in order to complete your physics assignment, you need a capacitor. How would you go about making one? Explain.
You can make a capacitor out of aluminum foil and some kind of insulating spacer, such as paper. Make a capacitor and then measure its capacitance.
Predict what will happen if you increase the distance between the aluminum
sheets.
2. Increase the distance between your Built capacitor (
one sheet of paper, two sheets etc
), holding the area
of plates constant. Measure the capacitance. Take at least 5 data points.
Q2.1: Did the capacitance change? If so, how did it change?
P 2.2: Predict what will happen if you decrease the area
of your capacitor.
3. Decrease the
area
of your Built capacitor (
by 1/2, 1/4, etc on both plates
) holding the distance
in between the plates constant. Measure the capacitance. (
Take at least 5 data points
). Did the capacitance change? If so, how did it change?
Display your 2 datasets in 2 tables and Plot 2 graphs by hand
, ONLY
: Capacitance vs the distance (
with paper Units
) in between and Capacitance vs area (
with real units
).
How area, A
and distance in between, d relates to Capacitance

: Inquiry into Capacitor Design
Directions: 1.
Using the first 2 tabs , voltmeter
, and battery
, find variables that are used to design a capacitor. 2.
Identify what you would maximize or minimize to make a capacitor with the greatest capacitance. Are there items in the sim that do not appear to affect the capacitance?
3.
Using the first 2 tabs , voltmeter
, and battery
, explore the relationships between charge, voltage, and stored energy for a capacitor. Summarize your findings. 4.
If you wanted to design a capacitor system to store the greatest energy, what would you use?
