What unit is used to measure capacitance?
Think of the unit of measure related to electric charge storage.
What does a capacitor do?
Consider functions in electric circuits.
What is the unit of capacitance?
It's related to charge storage.
True or False: A capacitor can only store charge when it's connected to a battery.
Think about how charging works.
A capacitor with 4 F capacitance is connected to a 10 V source. How much charge does it hold? Explain your reasoning.
Use the basic formula for charge stored.
If a capacitor discharges and releases 20 coulombs of charge, and it had 5 V initially, what was its capacitance?
Rearrange the formula for capacitance.
