If the work done by a battery to move a unit charge through the battery from one terminal to the other is doubled, what is the effect on the battery's emf?a. emf becomes zero. b. emf is halved.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

i will answer your question if you answer mine
