8.2: Capacitance and Capacitors
Figure 8.2.5 : A variable capacitor. For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor.
List of 25 Applications of Capacitors | Uses of Capacitors
Applications of Capacitors. Some typical applications of capacitors include: 1. Filtering: Electronic circuits often use capacitors to filter out unwanted signals. For example, they can remove noise and ripple from power supplies or block DC signals while allowing AC signals to pass through.
Why multiple capacitors in parallel?
The effective ESR of the capacitors follows the parallel resistor rule. For example, if one capacitor''s ESR is 1 Ohm, putting ten in parallel makes the effective ESR of the capacitor bank ten times smaller. This is especially helpful if you expect a high ripple current on the capacitors. Cost saving. Let''s say you need a large amount of ...
