current amplification การใช้

• They provide the majority of the current amplification ( while consuming low quiescent current ) and directly drive the load, connected via DC-blocking capacitor C2.
• This DVD in addition includes a video on current amplification by a three-electrode crystal, and also an audio recording of the conferral of an honorary doctorate on Ernest Rutherford in G鰐tingen by the Dean Max Born ( 1931 ).
• The common-emitter amplifier is designed so that a small change in voltage ( " V " in ) changes the small current through the base of the transistor; the transistor's current amplification combined with the properties of the circuit means that small swings in " V " in produce large changes in " V " out.
