When resistors are placed in series, the voltage across one resistor is (more/less/the same) than the voltage of the battery and the current through the circuit is (more/less/the same) than the current through a simple circuit. Therefore, the overall resistance of a circuit where resistors are placed in series is (higher/lower/the same) than the overall resistance of a simple circuit. When resistors are placed in parallel, the voltage across one resistor is (more/less/the same) than the voltage of the battery and the current going through the battery is (more/less/the same) than the current through a simple circuit. Therefore, the overall resistance of a circuit where resistors are placed in parallel is (higher/lower/the same) than the overall resistance of a simple circuit.

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.
