Capacitors Flashcards
1
Q
Units of capacitance
A
Farads (F)
2
Q
When a capacitor is discharging what does the current/time graph look like?
A
The current is negative and will decrease to zero. (This is due to the current flowing in the opposite direction as the electrons flow from the negative plate to the positive plate)
3
Q
How does the capacitance of a capacitor affect the charging/discharging time?
A
A greater capacitance = longer time to charge/discharge
