1
less than 1
between 20 and 500
above 500
Answer is Wrong!
Answer is Right!
The correct answer is: C. between 20 and 500.
Bipolar junction transistors (BJTs) are three-terminal semiconductor devices that can be used to amplify or switch electronic signals and electrical power. The value of à for a transistor is the ratio of the collector current to the base current. In other words, it

is a measure of how much current the transistor can amplify.
The value of à for a transistor can vary depending on the type of transistor, the manufacturing process, and the operating conditions. However, in general, the value of à is typically between 20 and 500.
Option A is incorrect because the value of à is typically greater than 1.
Option B is incorrect because the value of à is typically greater than 1.
Option D is incorrect because the value of à is typically less than 500.
