As you know, a capacitor has two terminals, and we measure capacitors in terms of capacitance. Capacitance (C) is the ability of a capacitor to store energy. The unit of capacitance is Farad. Let’s see some fundamental mathematics of capacitance. You can see that capacitance is the ratio of total charge and the voltage applied across the capacitor.
Measuring the time constant t approximately by counting the number of squares. Pulse width « 5 τ: In this case the capacitor does not have time to charge significantly before it is switched to discharge, and vice versa. Let the pulse width be only 1.0 τ in this case and set the frequency accordingly.
Pulse width is defined as the time between T2 and T1. The upper limit on these calculations can be extended to any set amount.
