Transistor Product function

Crystal transistor has the function of current amplification. Its essence is that the triode can control the large change of collector current with small change of base current. This is the most basic and important characteristic of the triode. We will Δ Ic/ Δ The ratio of Ib is called the current magnification of the crystal triode“ β” express. The current magnification is a fixed value for a certain triode, but it will change with the change of base current when the triode is working.
