Definition: Electrical device consisting of system of conductors and insulators arranged to store electric charge. * Critical component of flash-units: electric current from batteries are built up in the capacitor ready for electricity to be discharged into flash-tube.* Also known as electrical condenser. CCD capacities The CCD at the heart of all digital cameras and scanners is also essentially a multiple capacitor - one in which the charges built up in each little capacitor (the pixel) by incoming light is read off one-by-one to reconstruct the image.
