Question:easy

The bar graph below shows the failure rates, number of failures per thousand units, of different electronic components.
ComponentFailure Rate
Picture Tubes15
Signal Devices16
Capacitors20
Integrated Circuits30
Printed Circuit Boards33
Hybrid Micro Circuits40
From the failure data of electronic components presented here, which statement is true?

Show Hint

Check reliability using the failure rate, a lower failure rate means more reliable, a higher one means less.

  • Integrated circuits and Printed circuit boards are more reliable.
  • Capacitors are more reliable than picture tubes.
  • Higher number of component failures is likely to be due to picture tubes.
  • The least reliable component is Hybrid Micro circuits.
Show Solution

The Correct Option is D

Solution and Explanation

Ranking lowest to highest: Picture Tubes(15), Signal Devices(16), Capacitors(20), Integrated Circuits(30), PCB(33), Hybrid Micro Circuits(40). The highest bar = least reliable = Hybrid Micro Circuits.

Final Answer: Option (4).
