3 of 12> 4th Edition Part A Choose what is true about the "charge escalator" model for the battery The current inside the battery is opposite to that in the wire connecting the wires on the outside mInside the battery positive charge is removed from the positive terminal and deposited into the negative one. With no current the potential difference across the e battery equals its emf, and with current, the battery's potential difference is slightly more than the emf....
