WebThe energy stored in a capacitor is: \$ U = \frac {1} {2}CV^2 \$ Let's say you can charge that capacitor up to 5V. Then: \$ U = \frac {1} {2} 100\mu F (5V)^2 = 1.25 mJ\$ A watt (\$W\$) is one joule (\$J\$) per second. So if your load is \$1W\$, this capacitor can store enough energy to run it for \$1.25ms\$. WebWe can see from the above examples that a capacitor when connected to a variable frequency supply, acts a bit like a frequency controlled variable resistance as its reactance (X) is “inversely proportional to frequency”. At very low frequencies, such as 1Hz our 220nF capacitor has a high capacitive reactance value of approx 723.3KΩ (giving the effect …
