Question 168Electricity & Electronics - 1st Asst/Chief

The correct answer is A) the ammeter in series and the voltmeter in parallel with the resistance. This is the correct method because the ammeter must be connected in series with the resistance to measure the current flowing through it, while the voltmeter must be connected in parallel with the resistance to measure the voltage drop across it. This allows you to determine the resistance value using Ohm's law (R = V/I). The other options are incorrect because B) and C) do not correctly connect the meters to measure both current and voltage, and D) has both meters in parallel, which would not provide the necessary measurements to calculate the resistance.
