Direct Current examples listed include which set?

• A. Solar panel
• B. Generator
• C. Car battery, pager, flashlight
• D. Wind turbine

Answer: (C)

Direct current moves in a single direction, which is why it’s typical for battery-powered devices. A car battery supplies DC to the vehicle’s electronics, and pagers and flashlights run on the stored energy in batteries, delivering current in one steady direction. Solar panels do produce DC, but they’re a source of electricity rather than a device that runs on DC. Wind turbines and traditional generators usually generate alternating current, which reverses direction periodically. So the set that clearly shows direct current usage among these items is car battery, pager, and flashlight.
