Which value corresponds to the battery voltage?

• A. 12 Volts
• B. 28 Volts
• C. 48 Volts
• D. 24 Volts

Answer: (D)

The battery voltage is the nominal DC supply that powers the whole circuit. 24 volts is the best answer here because 24 VDC is a common standard for battery-powered control systems and equipment. It typically comes from two 12 V cells in series, which gives ample voltage to drive controllers, sensors, and modest motors without pushing current to still-unreasonable levels. In many diagrams and specifications, a 24 V DC bus is used for reliability and wiring efficiency, so the system described is most consistent with a 24 V supply. The other voltages—12 V, 28 V, and 48 V—are typical in different contexts (smaller loads, some aerospace/industrial applications, or higher-power systems), but for the usual battery-powered control setups referenced in this context, 24 volts is the standard match.
