hello
I am no transistor expert and i do have very limited experience with them. I am trying to understand how the base current is sized to a transistor. After doing some searching on google i understood that one have to look at the DC current gain (BETA) in order to calculate the (lb). But on the specification sheets like the 2n3055 they mention values like these, DC current gain= 20-70. I am not getting the picture here, should one chose a value between 20-70.
Would be thank full if some one could explain.
