Capacitance is the ability to store electrons and is measured in Farads.One Farad is a very large value! So most capacitors used in electronic circuits are measured in MicroFarads (uF) or even Picofarads (pF). Capacitance = Q / V Where Q is the charge and V is the voltage. Thus the capacitance is the charge divided by voltage. The important parameters of the capacitor are 1. Value -Value is marked on the capacitor directly or in colour codes 2. Tolerance -It indicates how much more or less the actual capacitance of the capacitor 3. Working voltage -It is the maximum voltage a capacitor can withstand before the dielectric breakdown 4. Leakage current .There is always small leakage current in all capacitors. Ideally this should be zero. But no capacitor is perfect without leakage current. Tantalum capacitor is comparatively better with minimum leakage current Value 1pf (Pico Farad) = 0.001nf (Nano Farad) 1nf (Nano Farad) = 0.001μf (Micro Farad) 1μf (Micro farad) =
