Which device in a vehicle powers tools by converting DC to AC?

• A. Transformer
• B. Inverter
• C. Generator
• D. Alternator

Answer: (B)

DC to AC conversion in a vehicle is done by an inverter. The car battery supplies DC, but many tools run on AC, so the inverter converts that battery power into usable AC voltage (like 120V or 230V, depending on the model). This lets you power tools from the vehicle when no mains power is available. The other devices don’t fit: a transformer only works with AC input, so it can’t create AC from DC; a generator or alternator produces electrical power from mechanical energy and, in a car, ultimately delivers DC after rectification rather than ready AC for tools. Use an appropriately rated inverter to match the tool’s wattage and include proper safety features.
