How would you diagnose a short to supply vs a short to ground in a sensor circuit using a multimeter?

• A. A short to supply shows near-zero resistance between input and ground.
• B. A short to supply shows near-zero resistance between input and supply; a short to ground shows near-zero resistance between input and ground; verify by isolating components and measuring continuity.
• C. Both scenarios show infinite resistance.
• D. There is no difference; both show high resistance.

Answer: (B)
