Simple power supply circuitPower Supply CircuitAlways begin with a very simple circuit and add on components later, if a more complex circuit is needed.Use easy to get, basic components, transformer.
Improper connections in circuit, can damage components. To reduce component damage, experiment first with dry-cell battery power sources and later go on to regular power supply.Use resistors between 1 kΩ and 100 kΩ. To avoid transistor damage and measurement errors.Before starting circuit construction, measure and record all component values.Make a schematic diagram of the circuit.Build the circuit on a board or any other non-electric conducting medium.Check each wire to its connection in the circuit and verify each one of them on the diagram for accuracy.Measure and solve all voltage and current values.Re-check the circuit and recalculate the current values.Tools to Build a Simple Power Supply CircuitPiece of boardFour diodesLM regulator .
