Capacitors Flashcards
1
Q
How do capacitors store energy?
A
In a magnetic field
2
Q
Capacitor plate area increases therefore
A
Capacitance increases
3
Q
How do capacitors add?
A
In series = inversely
Parallel = directly
4
Q
How does current add in a capacitive circuit?
A
In series = the same
In parallel = directly
5
Q
How do you find charge of a capacitor?
A
Q = E • C
6
Q
How do you find tau of a capacitor?
A
1 tau = R • C
7
Q
Which resistor do you use to find tau on a charge cycle?
A
The resistor in series with the source
8
Q
Which resistor do you use to calculate tau in the discharge cycle?
A
In parallel with the capacitor
