"For low power transistors (under 1 W), the current gain is typically 100 to 300. High power transistors (over 1 W) usually have current gain of 20 to 100." — Electronic principles by Malvino
I want to understand why the current gain is high for low power transistors and why it is low for high power transistors.
Besides, I want to know that why we are trying to control the collector current by the base current. What do we get out of controlling these currents.
