(a) A certain capacitor stores 50 microcoulombs (50 μC) with 10 V across its plates.What is its capacitance in units of microfarads?
(b) A 2.2 μF capacitor has 100 V across its plates. How much charge does it store?
(c) Determine the voltage across a 1000 pF capacitor that is storing 20 micro-coulombs (20 μC) of charge.
Question 12.1: (a) A certain capacitor stores 50 microcoulombs (50 μC) with...
(a)C=\frac{Q}{V}=\frac{50 \ \mu C}{10 \ V}= 5 \ \mu F
(b) Q = CV = (2.2 μF)(100 V) = 220 μC
(c)V=\frac{Q}{C}=\frac{20 \ \mu C}{1000 \ pF}=20 \ KV
