In general, a transistor amplifier is a circuit for amplifying an analog signal or a digital data carrier signal. For example, the output audio signal of a microphone is very weak and the audio oscillation is in a very low voltage range. With a transistor audio amplifier, its output can be increased to the standard…

A transistor is a three-pin electronic component which its main function is to pass the current from two pins according to the other pin (along with current amplification). Transistors have different types, but we are going to examine the bipolar type here. The two pins which the current passes are called the emitter (E) and…

In most of the books about the use of capacitors, it is written in such a way that the capacitor stores electric charge in itself and discharges it when necessary. What we need to know is when should the capacitors be charged and when should they be discharged and how is this possible? Therefore, first…

Resistor prevents additional voltage or current from entering the part in the circuit. The maximum allowed voltage or current of each part may be different from another part, if it exceeds, It will cause the overheat and the material of that part combines with oxygen and in the other words, the part burns. The resistor…
