Why is earthing of outer surface of a cylindrical capacitor needed? Briefly explain what happens inside of a dielectric after you insert it between the plates of the capacitor. Explain Faraday's correction to the Ampere's law(include the relevant equations). ...
Adding electrical energy to a capacitor is called charging; releasing the energy from a capacitor is known as discharging.Photo: A small capacitor in a transistor radio circuit.A capacitor is a bit like a battery, but it has a different job to do. A battery uses chemicals to store ...
Electric cars also use stored chemical energy, though they release it electrochemically, without any kind of combustion, as electrons ping from their slowly discharging batteries; there's no burning of fuel, no air pollution spewing from the tailpipe, and no obvious emissions of any kind are ...
I have looked at the rectified levels with a scope and it has a ripple of about 0.5V (p2p) at 20V (instead of the 16V specified in the schematic) - with a typical saw-tooth like wave form of the slowly discharging caps. The regulated +12V and -12V are very flat and I could not ...
How does the charging and discharging of capacitors happen? List three reasons why a dielectric is used in a capacitor. Why do you need to standardize the potentiometer wire? What are the requirements for a solid ionic conductor? Provide an example. Plumber's solder is composed of 67...
sometimes hundreds of times. You can recharge secondary batteries just by passing a current through them in the opposite direction to which it would normally flow (when it's discharging); you can't normally do this with primary batteries. When you charge yourcellphone, you are really just runn...
