What are typical power sources for a defibrillator?

• A. Battery power
• B. Wind-up mechanical power
• C. Steam power
• D. Solar power

Answer: (A)

Defibrillators rely on stored electrical energy from a battery. Portable AEDs and hospital units use battery packs so they’re ready to deliver a shock anywhere, without being plugged in. The device charges its internal capacitors from the battery to provide the required, rapid energy for defibrillation, making quick response possible in emergencies. Other power methods like wind-up, steam, or solar aren’t practical for defibrillators because they can’t guarantee immediate, reliable power in urgent clinical scenarios; they’re slow to generate energy or depend on environmental conditions, which would delay life-saving treatment. In many settings, equipment may recharge from mains power, but the actual defibrillation energy comes from the battery to ensure portability and readiness.
