WebThe negative terminal is actually at 0V, just like the Earth. Now, because of the chemicals in the battery, we still find the positive terminal is 12V higher than the negative terminal, at 12V. In the end, we moved the negative terminal from -500V to 0V, and the positive terminal from -488V to 12V. There's still a 12V difference between them. WebIn National 5 Physics examine the current and voltage in series and parallel circuits to formulate rules and determine unknown values.

Web8 May 2024 · The CC+CV mode I was writing about, doesn't trickle-charge indefinitely. When the battery reaches the voltage set, be it 4.2V or 4.0V, the charging ceases. It may trickle-charge at 4.195V, depending on exact design of the charging circuit, but setting a CV of 4.0V/etc means, stopping the current and not letting the battery voltage going any higher. thinkvape craton
