If the positive plate on a charged capacitor will pass current to the negative

[Ratch]

jim hardy,

A capacitor in that AC transients paper is 'energized' when in use because it's connected to its mains. "Charged" would be the wrong term because it's charged, discharged, and recharged opposite polarity with every line cycle.

Any capacitor imbued with energy is energized, and has a voltage across its terminals. All capacitors have the same net charge, specifically zero.

Sorry, but Esmeralda doesn't sound very credible.

Why not?

In my background, to "Charge" a capacitor implies to connect it to a source of DC and allow charge(Coulombs) to accumulate per Q = C*V . I do that sometimes just to see if it holds charge, ie checking its insulation resistance.
The energy stored is 1/2 C*V^2 and sometimes i'll short its leads and estimate from size of the spark whether its capacity seems intact. An analog meter is real handy for that test, observe how fast the cap discharges.

That capacitor holds a voltage. Its net charge is the same before and after it is energtized and shorted.

So given my background i was a mite puzzled by what appeared to be use of the terms interchangeably.

Not by me.

A cap that is charged has energy stored in its dielectric, but i was taught to call it charged. because it may not be connected to a power source anymore. Be careful when picking up capacitors...
One that's "energized" is definitely connected to a power source.

Connected or not, any cap with a voltage across its terminals in energized.

I'll remember those things when traveling in your world.

Esmeralda seems clueless how a flash works.

Step 1

Energize the capacitor by making the connection between the battery and the flash capacitor. When you make the connection between the battery and capacitor, the capacitor will begin to absorb the electricity that is being released by the flash battery. Most capacitor run flash cameras have either a light that shows the capacitor is full or a soft tone that builds as the capacitor is being filled. When the tone stops, the capacitor is ready to release enough energy to operate the flash.

The connection is from the battery to the step up voltage converter, which energizes it. Upon energization, the stepup converter commences charging the capacitor to somewhere in the 350 volt range.
The "tone" is its stepup transformer raising the voltage .
Connecting the battery to the capacitor would charge it to battery voltage, ~1.5 volts.

But its okay, you explained your terms clearly. I can understand you now.

jim hardy,Nevertamed,Is that a plea for help, or an acknowledgment that you are in over your head?

i don't need help for your obstinacy, i think you do

P.S. please don't argue about the definition of obstinacy, i know what will happen afterwards
