WebMar 1, 2024 · The transistor is not active but passive element; the only thing that it can do is to dissipate power. So, the transistor is not amplifying but attenuating element. It is just a "resistor" (non-linear, electrically controlled but still a resistor) that decreases the current. The true amplification is impossible; so there are no real amplifiers. WebFeb 1, 2024 · The current flow through the BJT (Ic) is controlled by the size of the base current (Ib). Every BJT has a particular ratio between the size of this 'collector' current and the 'base' current which is called current gain (beta).
