12 Volt 20 Amp Power Supply Circuit Diagram
There are two main types of power supplies: The Linear power supply is widely used. It is simple because circuits are not too complicated. But they are large and low-efficiency, at only about 50% or more. While they work, most energy lost is in the form of high heat.
Switching Power Supply Circuit Diagram Headcontrolsystem
The amount of current you can push through your circuit is determined by the total resistance of the circuit and the electrical pressure (Voltage) applied. So, you connect your circuit to a 12V battery and lets say 100mA of current flow through the circuit and all is well. you are still only applying 12V of pressure.
