yeah.
if you ever decide to study quantum and solid state physics, you will understand why we say holes are charge carriers. there is a very large and distinct difference between a freed electron from an ionized atom and an electron moving from one atoms valance shell to anothers. electricity is not electrons flowing in a copper river like you think it is.

I know OP probably has brain damage, but for those who's interested - when electric current was invented, it was decided that direction of current is the direction of positive carriers, but only later it was discovered that it's electrons - negative carriers - that actually move in the wire.

ive never studied vacuum tube transistors, but i dont think holes can travel across a vacuum, because then an electron in the valence band would have to cross the vacuum, and i dont think thats possible.

Quoted By:

>>14357961
Heat is used to liberate electrons from the cathode which are accelerated towards the anode by a positively charged control grid. In conventional current, the positive charge teleports across the vacuum through the positive grid, which should repel it. It is undoubtedly a negative charge being carried by electrons.

the label is arbitrary.

>>14356227
have you ever made a galvanic cell in chemistry class? electrons are flowing in the metal wire, and positive ions are flowing in the salt bridge.

plasmas are an example where both charge species participate in conduction.

holes are just another example, but in their case they aren't a fundamental particle.

Dude, I work for the power company. We sell you electrons.
Actually, the electrons go back to us, so we're only renting you electrons.
Um... it's alternating current, so we're renting you the same electrons you just had, 60 times a second.
Okay, got that?

Can anyone tell me what type of charger should I get for this kind of battery?

It says 7.4V --- 4.8aH / 35.52Wh
Should I get charger with exactly those specs or can I get for example 12V @ 3 aH that will output 36Wh?

The voltage needs to match or by close, like 7.6 V. The amperage can exceed 15 A if it's a switching power supply, which it probably will be. 12 V will damage the battery for sure.
