(B) Ohm's law states that the current $I$ flowing through a conductor is directly proportional to the potential difference $V$ across its ends,provided the physical conditions remain constant. Mathematically,$V = IR$,or $R = V/I$.To determine the resistance $R$ experimentally,we need to measure the potential difference across the resistor and the current flowing through it.$1$. $A$ voltmeter must be connected in parallel with the resistor $R$ to measure the potential difference $V$ across it.$2$. An ammeter must be connected in series with the resistor $R$ to measure the current $I$ flowing through it.Looking at the provided diagrams:- In option $B$,the voltmeter is connected in parallel with $R$ and the ammeter is connected in series with $R$. This is the correct configuration to measure both $V$ and $I$ simultaneously to calculate $R$ using $R = V/I$.

Which of the following wiring diagrams could be used to experimentally determine $R$ using Ohm's law? Assume an ideal voltmeter and an ideal ammeter.
