capacitor One of the most common users of the capacitor is flash cameraCapacitor: it is a device that has the abilityto store potential energy and electric charge by two conductors   has the same charge but opposite sign andcharge will transform from the positive plat to the negative During this process work must occur to transfer the charges throughthe potential difference between the conductor                            The symbols of the capacitor in electric circle    Equtions:C=q/vab   ; c is a capacitance , q is a charge, vab is a volte between a and bThe units of capacitance is F (farad)Also we can find a capacitance by C=£0A/d£0 is the permittivity in space andhas value 8.85×10^-12, A is area , d is thedistanceThe general equation for capacity that connected in  series; 1/Cequvelant=  For two capacitors C1,C2 connected  in series we haveCequvelant= c1*c2/c1+c2        The general equation forcapacity that connected        In parallel; cequvelant=                   C equvelant= c1+c2+c3+….Total work doneU=w=0.5q^2/c=0.5cv^2=0.
