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
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.
Battery ac or DC?
Batteries can provide both AC (alternating current) or DC (direct current) power, depending on the type of device they are connected to. However, most batteries themselves supply DC power. Devices that require AC power typically use an inverter to convert the battery's DC power into AC power.
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
Does a fluorescent ballast work in a DC V supply?
No, fluorescent ballasts are designed to work with AC voltage supplies. They require the alternating current to function properly and cannot operate on a direct current (DC) power source.
How does DC power work in a power plant?
DC power in a power plant is typically generated by converting the AC power produced by generators using rectifiers. This conversion process changes the alternating current into direct current, which is then used to power specific equipment or systems in the plant that require DC power, such as control circuits or certain types of motors. DC power offers benefits such as easier control and distribution over long distances compared to AC power.
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.
