Note that the ground terminal can not be used as a power terminal, the power terminal is only COM and V + two terminals, in addition to connecting the load is too large, may cause the power supply self-protection, there will also be a power supply indicator light flashes.
Through the transformer and rectifier, the alternating current into direct current device is called the power supply rectifier power supply. Electronic devices that can provide signals are called signal sources. A crystal transistor amplifies the signals sent in front of it and transmits the amplified signals to the circuits behind it.
