Capacitors Flashcards
1
Q
Capacitor
A
Component that stores charges, consisting of 2 plates separated by an insulator (dielectric)
2
Q
Exponential Decay
A
Constant-ratio process in which a quantity decreases by the same factor in equal time intervals
3
Q
Time Constant
A
Product of capacitance and resistance for a capacitor-resistor circuit. Time taken for p.d., current or charge to decrease to e^-1 of its initial value, when the capacitor discharges through a resistor.
