Question 1

What is a Capacitance Calculator?

Accepted Answer

A capacitor stores electrical energy in an electric field between two conductive plates separated by an insulating dielectric. Capacitance C (farads) measures how much charge Q is stored per unit voltage V: C = Q/V. Capacitors are used in power supplies for smoothing, in filters, timing circuits, and energy storage (supercapacitors).

Question 2

How does the Capacitance Calculator work?

Accepted Answer

Q = CV (charge = capacitance × voltage) Then: Energy stored: E = ½CV² (joules) Then: Capacitors in parallel: C_total = C₁ + C₂ + ... Then: Capacitors in series: 1/C_total = 1/C₁ + 1/C₂ + ....

Question 3

Can you give an example of how to use the Capacitance Calculator?

Accepted Answer

Example: Input 100 μF capacitor, 12 V gives a result of Q = 100×10⁻⁶ × 12 = 1.2 mC; E = ½ × 100×10⁻⁶ × 144 = 7.2 mJ.
