Homework Help: Questions and Answers: Transistors used in electronic devices performed functions similar to vacuum tubes, but they were larger and more power hungry.
a) True
b) False
Answer
Let’s understand what transistors are:
- Transistors are semiconductor devices that can amplify or switch electronic signals
- They were invented in 1947 at Bell Labs
Compare transistors with vacuum tubes Transistors:
- Smaller in size
- More energy efficient (consume less power)
- More reliable
- Generate less heat
- Longer lifespan
Vacuum tubes:
- Larger in size
- Less energy efficient (consume more power)
- Less reliable
- Generate more heat
- Shorter lifespan
Explanation:
- Transistors are smaller and more energy-efficient than vacuum tubes, which is why they replaced vacuum tubes in electronic devices.
- Vacuum tubes were larger, consumed more power, and produced more heat.
- Transistors, introduced in the mid-20th century, provided similar electronic functions (amplifying signals, switching, etc.) but with greater efficiency, smaller size, and lower energy consumption.
Final Answer:
- The statement is incorrect on both counts
- Transistors are actually smaller and more energy efficient than vacuum tubes
- These advantages of transistors were key reasons why they replaced vacuum tubes in electronic devices
Therefore, the answer is (b) False.
The statement is false because transistors are actually smaller in size and more energy efficient compared to vacuum tubes.
