Chapter 24 Flashcards
Capacitance
1
Q
Definition of capacitance
A
The measure of ability of a capacitor to store energy and charge
C = Q/V
2
Q
Capacitor
A
2 metal conductors separated
3
Q
Energy storage in cpacitors
A
U = Q^2/2C
4
Q
Capacitor eq for efficiencies
A
C = e0 A / d
thus to optimize: large plate small distance between
5
Q
Charges on capacitors when switch closed
A
