an unmarked battery has unknown internal resistance if the battery is connected to a fresh 5.60 volt battery positive to positive and negative to negative the current through the circuit is 10.0ma if the polarity of the unknown battery is reversed the current increase to 250ma determine the source voltage and internal resistance of the unknown battery assume that in each case the direction of the current is negative to positive in the 5.60v battery

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
