When checking an open circuit with an analogue meter, what resistance reading would you get?

• A. Zero
• B. 5 ohms
• C. 100 ohms
• D. Infinity

Answer: (D)

When checking an open circuit with an analogue meter, the resistance reading that you would obtain is infinity. An open circuit means that there is a break in the circuit, and there is no continuous path for current to flow. This absence of conductivity results in an infinite resistance, which the analogue meter will indicate as a high value or infinity on its scale. In practical terms, when the circuit is open, the connections are not complete, and hence, the meter cannot detect any flow of electricity between the points being measured. This reading serves to confirm that the circuit is indeed open, as any finite reading would suggest that there is a path present for current to pass through.
