What three voltages are commonly supplied by power supplies to computer components? (Choose three.)

• A. 1.5 volts, 5 volts, and 12 volts
• B. 3.3 volts, 5 volts, and 12 volts
• C. 2.5 volts, 7.5 volts, and 14 volts
• D. 3.0 volts, 9 volts, and 15 volts

Answer: (B)

The correct answer identifies the voltages commonly supplied by power supplies to computer components: 3.3 volts, 5 volts, and 12 volts. These voltages are crucial for powering different parts of a computer. The 12-volt supply typically powers components such as the CPU and video cards, which require higher energy. The 5-volt line is often used for logic circuits, standard logic chips, and peripheral components like USB devices. The 3.3-volt supply is frequently used for the motherboard and low-power components, ensuring efficient operation without overheating. Understanding these standard voltages is essential for anyone working with computer hardware, as they form the backbone of voltage requirements for various components and prevent damage or malfunction when installing or replacing parts.
