capacitor - What do you call it when you add energy to an inductor?


When you add energy to a capacitor, you say that you are "charging it". (This is kind of a misnomer, since the total amount of charge in the capacitor is the same, but whatever.)


But what do you call it when you put current through an inductor, and it ________es up and forms a magnetic field?


Edit: Actually, using "charge" for a capacitor is not a misnomer, as shown below and in 'charge' etymology, though it leads to confusion, with people mistakenly thinking that capacitors store electric charge, when in actuality, the charge of energy just moves the electric charge from one plate to the other.



Answer



The word is simply energizing. It is actually used quite often when referring to superconducting magnets, which are nothing but inductors. http://en.wikipedia.org/wiki/Superconducting_magnet#Persistent_mode

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
