A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating …
Capacitive Voltage Divider as an AC Voltage Divider
The ckt works fine if I use standard 2 x 0.1 uF capacitors, but does not work when I use my home made capacitors. The Vss supply voltage is 5 volts peak to peak, at 2.6 MHz, while I get voltage across each capacitor (as shown on O''scope) is only 240 mV
7805
Looking at the datasheet I can see that the voltage regulators are not just a zenner diode inside, they are complex devices. I have noticed that there is always a capacitor at the input and another one at the output. An …

Why Single-Phase Induction Motors Need Capacitors
This is why low loss polymer capacitors are used as run capacitors because of a longer life time and lower loss of current, opposed to electrolytic capacitors which are ideal for momentary use. Run capacitors come in …
Polarised capacitor vs. unpolarised capacitor. Which to use when?
Tiny SMD capacitors (not polarized) have very low ESR so are used to filter out RF noise, and are often less than 1/4 inch from the device that needs them. In DC power supply feeds both polarized and non-polarized are used and safe as long as polarized capacitors are inserted correctly and no capacitor is exposed to a voltage …
