Capacitance of a Capacitor
The capacitance of a capacitor is the ability of a capacitor to store an electric charge per unit of voltage across its plates of a capacitor. Capacitance is found by dividing electric charge with voltage by the formula C=Q/V. Its…

Difference between Analog and digital signal
There is a key difference between analog and digital signals. An analog signal is a signal generated by an electromagnetic phenomenon that can be represented by a continuous mathematical function with amplitude and period as a function of time, while…

what is difference between impedence and reactance?
Circuits with capacitors and inductors are more complicated than the resistive circuits we talked about earlier, in that their behavior depends on the frequency: A “voltage divider ” containing a capacitor or inductor will have a frequency dependent division ratio.…
