Q1: What is a capacitor?
A1: A capacitor is a two-terminal element whose current through its terminals is proportional to the time rate of change of voltage across it. The proportionality constant is called capacitance (C).
$i=C\frac{dv}{dt}$
Q2: What determines capacitance?
A2: Capacitance is determined by the composition and geometry of the capacitor.
Q3: How do I simplify capacitors in series?
A3: Capacitors in series add like resistors in parallel.
Q4: How do I simplify capacitors in parallel?
A3: Capacitors in parallel add like resistors in series.
