6.1 - Capacitors Flashcards
1
Q
What is a Capacitor?
A
A circuit component that stores energy by separating charges into two electrical conductors with an insulator between them.
2
Q
What is Capacitance?
A
The quantity of charge which can be stored per unit potential difference across the plates of the capacitor
3
Q
What is the unit of Capacitance?
A
Farad (F)
4
Q
What is one Farad equal to?
A
One Coulomb per volt
5
Q
What is the equation for Capacitance?
A
Q/V
6
Q
What is Exponential Decay?
A
When the quantity decreases at a rate that is proportional to the magnitude of the quantity at that time
7
Q
What is the Time Constant?
A
The time taken for the charge remaining on a capacitor to decrease to 1/e (about 37%) of its initial value
8
Q
What is the equation for the Time Constant?
A
T=CR
