An Adjustable Power Supply Using Two Amp

This is a circuit for power supply that has an output of 0v to 12v at 700mA with a transformer that is rated at 1-amp (such as M-2155) or 1.4amp for a transformer that is rated at 2-amp (such as M-2156). This is a simple design for power supply. This power supply can adjusted. This is the figure of the circuit.Operation of the circuit is begin, first the mains voltage is reduced to a usable level
