What is the magnification and effect of these tubes?
The tube has a high current amplification factor, and a larger collector current can be obtained with a smaller base current. The basic circuit or those three, that is, the magnification becomes larger..
The amplification of these tubes is approximately equal to the amplification of the first tube and is multiplied by the amplification of the second tubes..
In addition, in detail, such a connection affects the input resistance of the circuit. Is the input resistance larger.
