A DC power supply is the following components: 1) A step down transformer to reduce the incoming 120 (or 240) V to a lower level, say 12VAC. 2) A rectifier which converts the AC waveform to a pulsed DC waveform. 3) A filter which smooths out these pulses to a more steady-state signal. 4) A voltage regulator, be it a zener diode or LMxxxx voltage regulator, which keeps the output at a consistent level.
What else can I help you with?
What are the safety precautions in using breadboard?
Never work on a circuit while the power supply is on.
Is a 24VDC power supply short-circuit protected?
That would depend on the power supply.
What is regulated power power supply?
is an embedded circuit or stand alone unit the function of which is to supply a stable voltage to a circuit or device that must be operated within certain power supply limits .
A device or circuit that provides power to the rest of the circuit or system is called what?
A device or circuit that provides power to the rest of the circuit or system is called a power supply,
When power fails in electronic circuit where do l start tracing fault?
Start at the supply and work toward the load.
Why is a power supply even after the power supply has been disconnected?
because the power still are in circuit of the motherboard and you have to drain the system
How is a series circuit and a parallel circuit alike?
Both take current and energy from the power supply and dissipate power.
What is the current called when it flows from and back to the power supply in a parallel circuit?
The current that flows from and back to the power supply in a parallel circuit is called branch current. Each branch in a parallel circuit has its own current flow that combines to form the total current drawn from the power supply.
What should a complete circuit have a minimum of?
a power supply (eg: battery) and a load (eg: resistor) even a piece wire shorting two terminals of the power supply is a closed circuit
Why ghost power acting on a circuit?
Ghost power may be acting on a circuit if it has a capacitor or transformer connected. This will supply power long after the input has been disconnected.
What is the function of neutral wires?
to complete the circuit and back to power supply
How does power supply failure alarm circuit works?
Power supplies don't fail. Idiot.
