AC Chapter 5: Capacitive Reactance and Impedance
AC capacitor circuits. Capacitors do not behave the same as resistors. Whereas resistors allow a flow of electrons through them directly proportional to the voltage drop, capacitors oppose changes in voltage by drawing or supplying current as they charge or discharge to the new voltage level. The flow of electrons "through" a capacitor is directly proportional …

3.2: Rectification
The most straightforward method to achieve this is to add a capacitor in parallel with the load. The capacitor will charge up during the conduction phase, thus storing energy. When the diode turns off, the capacitor will begin to discharge, thus transferring its stored energy into the load. The larger the capacitor, the greater its …
Discharging a capacitor
Since the Arduino constantly supplied 3.3 V to the circuit, after discharging, the voltage over the capacitor did not vanish, but remained finite at a fraction of of the applied voltage. The time constant of the discharging process did not depend on the voltage, but the connection to the Arduino opened up an additional discharging …

AC Capacitance and Capacitive Reactance
From the voltage and current waveforms and description above, we can see that the current is always leading the voltage by 1/4 of a cycle or π/2 = 90 o "out-of-phase" with the potential difference across the capacitor because of this charging and discharging process. Then the phase relationship between the voltage and current in an AC ...

Equations for discharge: The time constant we have used above can be used to make the equations we need for the discharge of a capacitor. A general equation for exponential decay is: For the equation of capacitor discharge, we put in the time constant, and then substitute x for Q, V or I: Where: is charge/pd/current at time t
Capacitors in Series and Parallel
Capacitors can be arranged in two – orientations, either in series or parallel connections. Suppose the capacitors are connected one after the other such that the negative terminal of the first connects to the positive terminal of the second. In that case, it …
