Capacitor is a voltage storing device it is store the charge in the form of voltage this is block the DC (Direct current) current and pass the AC (Alternating current 230V) current
Different types of capacitors such as :-
- Ceramic capacitor
- Polyester capacitor
- Non polarized capacitor
- Electrolytic capacitor
The unit of capacitor is Farad , it is measured in farad the farad name is given by the
British physician Michael Faraday
Farad is a very large unit it has
a different parts such as , micro farad , nano farad , and Pico farad
- 1) micro farad (uF) :- 1uF = 1/1 000.000 = 0.0000001 = 10^-6 F
- 2) nano farad (nF) :- 1nF = 1/1 000.000.000 = 0.000000000 = 10^-9F
- 3) Pico farad (PF) :- 1PF = 1/1 000.000.000.000 = .000000000000 = =10^-12
The capacitor works on different types of voltage rating if it is cross that pic voltage level then capacitor is blast when the capacitor connect the battery it is store the charge after charging capacitor connect the any electrical device it will discharge
The capacitor works on AC (Alternating current) as well as DC(Direct current)
- In DC supply the capacitor connect in series with any electronics device ,this device work only during the charging of capacitor when capacitor is charge the then the device is stop the working because the property of capacitor it is block the DC voltage
- The capacitor will connect in parallel in DC supply there will be no effect on the electronic device it is continually ON condition because DC supply will not filter in this condition
- In AC supply capacitor connect in series with device these device will fluctuate and continusly on and off there is not capture from human eyes
- When the
capacitor connect in parallel in AC supply then it will block the current and device will be fully off
- This capacitors are most used I rectifier because converting AC supply in to a DC supply efficiently and capacitor is work like filter on the rectifier circuit
