capaitors Flashcards
1
Q
Capacitor
A
Circuit component that stores energy by separating charges onto two electrical conductors with an insulator in between.
2
Q
Capacitors in parallel
A
or capacitors connected in parallel, the total capacitance is found as:
C=C1+C2+C3+…
3
Q
Capacitors in series
A
n series the total capacitance can be calculated using the following equation:
1/C=1/C1+1/C2+1/C3+…
4
Q
Time constant
A
The time constant is the time it takes for the charge on a capacitor to decrease to1/e (about 37%).
The two factors which affect the rate at which charge flows are resistance and capacitance. This means that the following equation can be used to find the time constant:
