A battery that has internal resistance is joined to a fixed resistor, an ammeter and a voltmeter, as illustrated. That battery is then swapped for another battery with the same electromotive force (e.m.f.) but a larger internal resistance. What change occurs in the ammeter reading and the voltmeter reading?
- Aammeter reading decreases, voltmeter reading decreases
- Bammeter reading decreases, voltmeter reading stays the same
- Cammeter reading stays the same, voltmeter reading decreases
- Dammeter reading stays the same, voltmeter reading stays the same
