PhysicsNEET 2019Ohm's law, resistivity, temperature dependence

Current Electricity

Circuit 1 has a 10 V source driving current $i_{1}$ through $a 10Ω$ resistor, with an ideal ammeter $A_{1}$ in series and an ideal voltmeter $V_{1}$ connected across the resistor-and-ammeter combination. Circuit 2 has the same 10 V source, $10Ω$ resistor and current $i_{2}$ , with ideal ammeter $A_{2}$ in series, but this time ideal voltmeter $V_{2}$ is connected across the resistor alone (not including the ammeter). The readings of the voltmeters and ammeters will be:

A. $V_{2} > V_{1}$ and $i_{1} = i_{2}$
B. $V_{1} = V_{2}$ and $i_{1} > i_{2}$
C. $V_{1} = V_{2}$ and $i_{1} = i_{2}$ ✓
D. $V_{2} > V_{1}$ and $i_{1} > i_{2}$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
