Question

which diagram shows the correct settings to measure resistance with a multimeter

a.

b.

c

d. not shown

○ c

○ d

○ b

○ a

Explanation:

To measure resistance with a multimeter, the component (resistor) must be disconnected from the circuit (power source), and the multimeter should be set to the resistance (ohmmeter) mode, with probes connected across the resistor.

• Option A: The resistor is still in a circuit with a power source (battery), so this is incorrect (measuring resistance requires the component to be isolated from the circuit power).
• Option B: The probes are connected to what appears to be a terminal or non - resistor component, and the setup doesn't show a resistor being measured.
• Option C: The resistor is isolated (disconnected from the circuit power), and the multimeter probes are connected across the resistor, which is the correct setup for measuring resistance.
• Option D: Since option C is correct, D is incorrect.

Answer:

C
