In the circuit shown, the cell has an emf of 12 V and an internal resistance which is not negligible.
When the resistance of the variable resistor is 10 Ω the voltmeter reads 10 V and the ammeter reads 1.0 A.
The resistance of the variable resistor is changed to 5 Ω.
What is the new reading on the ammeter?
