What condition must be met for a drill/driver to operate?

• A. Charged battery
• B. Plugged into a power outlet
• C. Requires a high-torque setting
• D. Lubricated chuck threads

Answer: (A)

Power is needed to run the motor, and for cordless drills this power comes from the battery. A charged battery installed provides the voltage and current the motor needs to start and operate. Without a charged battery, the tool won’t run even if you press the trigger. A high-torque setting changes how hard it drives a fastener, not whether the tool can start. Lubricating the chuck threads is a maintenance step for longevity, not a condition for operation. While a corded drill must be plugged in to operate, the scenario here emphasizes cordless use, so a charged battery is the essential requirement.
