CAPACITORS
CAPACITANCE
-
Unit for capacitance is farad, F
his formula is: 
Capacitance orientation in series
capacitance orientation in parallel
DIELECTRIC
Ke : dielectric factor, there are different dielectric constant and dielectric strength.

RC circuit
RC circuit: discharging
- As the switch s is closed, electron from negative plate flow through the resistor R to the positive plate. The charge neutralize one another. As the charge stored in the capacitor decreases, the potential difference v capacitor across the capacitor decreases.
- Finally, when the charge totally neutralize one another, the potential difference v capacitor drops to zero. the capacitor is now fully discharged.
RC circuit: changing
- As the switch s is closed, charge flow through the resistor R into the capacitor. as the charges start to build up into the capacitor, a potential difference v capacitor develop across the capacitor.
- Finally when this potential v capacitor equals to the voltage v of the supply, the voltage oppose each other and the charge stop flowing. the capacitor is now fully charged.
- capacitors are device that can store electric energy
-
his symbol is:
