The mains to the house is an alternating current and this high voltage is stepped down using a transformer. The low voltage secondary alternating current is converted to direct current using 4 diodes wired as a bridge rectifier. The 'lumpy' direct current is smoothed using an electrolytic capacitor to smooth the resulting dc. It may need to be voltage regulated if the circuits it feeds are voltage sensitive.

How does auto transformer work with DC supply?
Transformers don't work with DC supplies - they only work on AC.
What are the two main types of uninterrupitle power supplies?
DC and AC
How does DC power work in a power plant?
well u just have to fart and it will work ugly person
What are direct-current power supplies?
Dc Power Supplies converts AC to DC Two Main types 1)Linear : A simple circuit with diodes and capacitors 2)Switched Mode: sampling technique is used to convert AC to DC.
Do laptop work on ac or DC and how?
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
How can a radio use both DC and AC?
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
What computer power supplies transform AC to low DC?
ATX computer power supplies provide low volts DC of less than five volts. AT computer power supplies provide low DC only to five and twelve volts.
A power source can deliver what two types of current?
Power supplies can supply AC or DC current.
How does DC to ac power supply work?
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
What supplies power to a computer?
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
Are fans in computers ac or DC?
the work is done in the power supply box (the metal box part in the computer, the one you plug the power cord into). It converts AC to DC via transformers, rectifiers, and voltage regulators and has extra circuitry in there to make sure that the voltage doesn't ripple (with the changes in the AC voltage) or spike (e.g., when you first turn it on)
Why chokes are used in electrical circuits?
commonly with a single dc power source to isolate ac loads from other parts of the circuits. in dc power supplies to remove ripple
