Although modern manufacturing technology allows capacitors to be made extremely small and high-capacity, you can make your own capacitors at home with common household materials! A capacitor is made of two conductive plates with a gap in-between. When electric charge builds up on one plate, it causes the opposite charge to build up on the other.
The physical size and form factor of a capacitor are critical considerations, especially in space-constrained applications. Choose a capacitor that fits within the available space while meeting the electrical requirements of your circuit. How to calculate capacitor size?
Step 1: Gather the Materials You will need the following materials to create your capacitor: – Aluminum foil – A plastic sheet or wax paper – A pair of scissors or a utility knife – Insulating tape (such as electrical tape) – Some wire for connecting the capacitor to other components Step 2: Cut the Foil and Plastic Sheet
When sizing a capacitor, always choose one with a voltage rating higher than the maximum voltage in your circuit to prevent breakdown and damage. The capacitance value, measured in farads (F), indicates the amount of charge a capacitor can store for a given voltage.
A capacitor’s capacitance depends on the size of its plates, its dielectric material, and the separation between plates. It’s given by the following formula, where C is the capacitance: In essence, the bigger the plates, the closer they are, and the better the dielectric, the bigger the capacitance.
Charge it up, by applying the voltage from an ordinary household battery, to both terminals. After a few seconds disconnect the battery and connect the voltmeter to the terminals of the capacitor. Any reading (mV-V) will indicate a charge. Congratulations, you have a working capacitor, capable of holding an electric charge!
