Which of the following is not an advantage of electronic sensors?

• A. High accuracy
• B. Low power handling ability
• C. Fast response
• D. Long life

Answer: (B)

Electronic sensors are valued for precision, speed, and durability, thanks to their solid‑state design and lack of moving parts. High accuracy comes from semiconductor sensing and precise calibration, allowing reliable measurements. Fast response is possible because electronic signals can be processed and transmitted in microseconds, enabling real-time control. Long life follows from having few mechanical wear components, which reduces maintenance and replacement needs.

The option describing low power handling ability isn’t an advantage because it implies a limitation on how much power the sensor can safely manage. In practice, sensors are often selected for low power consumption to fit energy budgets and reduce heat, but having poor power handling would constrain use in many systems. So, choosing a sensor that can handle higher power or operate efficiently at low power aligns with the typical strengths of electronic sensing, making low power handling a disadvantage rather than an advantage.
