The statement 'A short circuit occurs when there is very little resistance and a large amount of current flow' is:

• A. False
• B. True
• C. Not necessarily
• D. Depends on voltage

Answer: (B)

The key idea here is how current responds to resistance when a voltage is present. A short circuit creates a path with very low resistance that bypasses the normal load. Ohm’s law tells us that current equals voltage divided by resistance, so when resistance is very small, the current becomes very large. That surge of current is the hallmark of a short circuit, so describing it as a situation with little resistance and a large current flow is accurate. In real circuits, the actual current is limited by the source and wiring, but it’s still much higher than normal, which is why fuses or breakers trip and components can overheat.
