Question $24$

If you double the current through a battery, is the potential difference across a battery doubled?

Reminder: All light bulbs, resistors, and batteries should be considered identical unless you are told otherwise. Any battery is assumed to be ideal; that is$,$ the internal resistance of the battery is negligible. In addition, assume the wires have negligible resistance. Ignore any change in resistance in a light buib flament when it heats up$.$

Answer:

Yes, because Ohm's law says $V=IR$

Yes, because as you increase the resistance, you increase the potential difference

No$,$ because as you double the current, you reduce the potential difference by half

No$,$ because the potential difference is a property of the battery

No$,$ because the potential difference is a property of everything in the circuit
