Power Supply usually it refers to the source of electricity. It could be a system or device for supplying electric power, or other device capable of providing energy to the load output of the power supply.
Power supply to other forms of energy into electrical energy device called a power supply.
Generator can convert mechanical energy into electrical energy, batteries can convert chemical energy into electrical energy generator battery itself is not charged, its positive and negative charges respectively poles, positive and negative charge generated by the voltage (current voltage is under the effect of the charge directional movement formed), there would have been in charge of the conductor to produce current only voltage can, when the battery is connected to the conductor to generate electricity poles and the release of positive and negative charge out, when the charge is dissipated, also do you charge flow (pressure) disappeared. batteries and other known power supply. Through the transformer and rectifier, the alternating current into direct current power supply device called a rectifier power. To provide an electronic device called a signal source. Transistor can be amplified signal sent, again amplified signal is transmitted to the back of the circuit to go. Transistor on the back of the circuit can also be seen as a signal source. Rectifier power supply, sometimes called the power supply source.
