Which statement best describes the typical characteristics of transistors?

• A. Large and power-hungry
• B. Delicate and high power
• C. Small, low power, and long-lasting
• D. Expensive and heavy

Answer: (C)

Transistors are small, solid-state devices that act as switches or amplifiers in electronic circuits. They’re designed to operate with very little power and to generate only modest heat, especially when compared to older technologies like vacuum tubes. Because they have no moving parts, they’re rugged and reliable, which translates to a long service life. These characteristics—tiny size, low power consumption, and durability—are what make transistors so foundational for compact, efficient electronics. That’s why the statement describing them as small, low power, and long-lasting is the best fit. The other descriptions imply large size, high power needs, fragility, or weight and cost that aren’t typical of common transistors.
